So to overcome this error, download winutils.exe and place it in any location.(for example,) Download winutils.exe for 64 bit. Set HADOOP_HOME to the path of winutils.exe. For example, if you install winutils.exe in D. Setting up your local machine using a QuickStart VM or Docker Image will give you examples of how to get started with some of the tools provided in CDH and how to man. Hadoop requires native libraries on Windows to work properly -that includes to access the file:// filesystem, where Hadoop uses some Windows APIs to implement posix-like file access permissions. This is implemented in HADOOP.DLL and WINUTILS.EXE.

Simple Solution:Download it from here and add to $HADOOP_HOME/bin

(Source)

IMPORTANT UPDATE:

For hadoop-2.6.0 you can download binaries from Titus Barik blog >>.

I have not only needed to point HADOOP_HOME to extracted directory [path], but also provide system property -Djava.library.path=[path]bin to load native libs (dll).

If we directly take the binary distribution of Apache Hadoop 2.2.0 release and try to run it on Microsoft Windows, then we'll encounter ERROR util.Shell: Failed to locate the winutils binary in the hadoop binary path.

The binary distribution of Apache Hadoop 2.2.0 release does not contain some windows native components (like winutils.exe, hadoop.dll etc). These are required (not optional) to run Hadoop on Windows.

So you need to build windows native binary distribution of hadoop from source codes following 'BUILD.txt' file located inside the source distribution of hadoop. You can follow the following posts as well for step by step guide with screen shot

If you face this problem when running a self-contained local application with Spark (i.e., after adding spark-assembly-x.x.x-hadoopx.x.x.jar or the Maven dependency to the project), a simpler solution would be to put winutils.exe (download from here) in 'C:winutilbin'. Then you can add winutils.exe to the hadoop home directory by adding the following line to the code:

Source: Click here

The statementjava.io.IOException: Could not locate executable nullbinwinutils.exe

explains that the null is received when expanding or replacing an Environment Variable. If you see the Source in Shell.Java in Common Package you will find that HADOOP_HOME variable is not getting set and you are receiving null in place of that and hence the error.

So, HADOOP_HOME needs to be set for this properly or the variable hadoop.home.dir property.

Hope this helps.

Thanks,Kamleshwar.

I just ran into this issue while working with Eclipse. In my case, I had the correct Hadoop version downloaded (hadoop-2.5.0-cdh5.3.0.tgz), I extracted the contents and placed it directly in my C drive. Then I went to

Eclipse->Debug/Run Configurations -> Environment (tab) -> and added

variable: HADOOP_HOME

Value: C:hadoop-2.5.0-cdh5.3.0

You can download winutils.exe here: http://public-repo-1.hortonworks.com/hdp-win-alpha/winutils.exe

Then copy it to your HADOOP_HOME/bin directory.

Winutils.exe is used for running the shell commands for SPARK. When you need to run the Spark without installing Hadoop, you need this file.

Steps are as follows:

Mechwarrior vengeance download. Mechwarrior 4 vengeance free download - MechWarrior 4: Vengeance Update, MechWarrior 4: Vengeance - Polar Tundra map, MechWarrior 4: Vengeance - Bio.

  1. Download the winutils.exe from following location for hadoop 2.7.1https://github.com/steveloughran/winutils/tree/master/hadoop-2.7.1/bin[NOTE: If you are using separate hadoop version then please download the winutils from corresponding hadoop version folder on GITHUB from the location as mentioned above.]

  2. Now, create a folder 'winutils' in C: drive. Now create a folder 'bin' inside folder 'winutils' and copy the winutils.exe in that folder. So the location of winutils.exe will be C:winutilsbinwinutils.exe

  3. Now, open environment variable and set HADOOP_HOME=C:winutil[NOTE: Please do not addbin in HADOOP_HOME and no need to set HADOOP_HOME in Path]

Your issue must be resolved !!

winutils.exe are required for hadoop to perform hadoop related commands. please download hadoop-common-2.2.0 zip file. winutils.exe can be found in bin folder. Extract the zip file and copy it in the local hadoop/bin folder.

I was facing the same problem. Removing the bin from the HADOOP_HOME path solved it for me. The path for HADOOP_HOME variable should look something like.

System restart may be needed. In my case, restarting the IDE was sufficient.

Set up HADOOP_HOME variable in windows to resolve the problem.

You can find answer in org/apache/hadoop/hadoop-common/2.2.0/hadoop-common-2.2.0-sources.jar!/org/apache/hadoop/util/Shell.java :

AndyAndy
  1. Download [winutils.exe]
    From URL :
    https://github.com/steveloughran/winutils/hadoop-version/bin
  2. Past it under HADOOP_HOME/bin
    Note : You should Set environmental variables:
    User variable:
    Variable: HADOOP_HOME
    Value: Hadoop or spark dir

In Pyspark, to run local spark application using Pycharm use below lines

Arma 3 altis life single player download. We have decided to create a mod for Arma 3 on the Atlis map for RPG. Buildings will be enter-able.

NarsireddyNarsireddy

I was getting the same issue in windows. I fixed it by

  • Downloading hadoop-common-2.2.0-bin-master from link.
  • Create a user variable HADOOP_HOME in Environment variable and assign the path of hadoop-common bin directory as a value.
  • You can verify it by running hadoop in cmd.
  • Restart the IDE and Run it.

Download desired version of hadoop folder (Say if you are installing spark on Windows then hadoop version for which your spark is built for) from this link as zip.

Extract the zip to desired directory.You need to have directory of the form hadoopbin (explicitly create such hadoopbin directory structure if you want) with bin containing all the files contained in bin folder of the downloaded hadoop. This will contain many files such as hdfs.dll, hadoop.dll etc. in addition to winutil.exe.

Now create environment variableHADOOP_HOME and set it to <path-to-hadoop-folder>hadoop. Then add;%HADOOP_HOME%bin; to PATH environment variable.

Open a 'new command prompt' and try rerunning your command.

I used 'hbase-1.3.0' and 'hadoop-2.7.3' versions. Setting HADOOP_HOME environment variable and copying 'winutils.exe' file under HADOOP_HOME/bin folder solves the problem on a windows os.Attention to set HADOOP_HOME environment to the installation folder of hadoop(/bin folder is not necessary for these versions).Additionally I preferred using cross platform tool cygwin to settle linux os functionality (as possible as it can) because Hbase team recommend linux/unix env.

I am new to Hadoop and have run into problems trying to run it on my Windows 7 machine. Particularly I am interested in running Hadoop 2.1.0 as its release notes mention that running on Windows is supported. I know that I can try to run 1.x versions on Windows with Cygwin or even use prepared VM by for example Cloudera, but these options are in some reasons less convenient for me.

Having examined a tarball from http://apache-mirror.rbc.ru/pub/apache/hadoop/common/hadoop-2.1.0-beta/ I found that there really are some *.cmd scripts that can be run without Cygwin. Everything worked fine when I formated HDFS partition but when I tried to run hdfs namenode daemon I faced two errors: first, non fatal, was that winutils.exe could not be found (it really wasn't present in the tarball downloaded). I found the sources of this component in the Apache Hadoop sources tree and compiled it with Microsoft SDK and MSbuild. Thanks to detailed error message it was clear where to put the executable to satisfy Hadoop. But the second error which is fatal doesn't contain enough information for me to solve:

Looks like something else should be compiled. I'm going to try to build Hadoop from the source with Maven but isn't there a simpler way? Isn't there some option-I-know-not-of that can disable native code and make that tarball usable on Windows?

Thank you.

UPDATED. Yes, indeed. 'Homebrew' package contained some extra files, most importantly winutils.exe and hadoop.dll. With this files namenode and datanode started successfully. I think the question can be closed. I didn't delete it in case someone face the same difficulty.

UPDATED 2. To build the 'homebrew' package I did the following:

  1. Got sources, and unpacked them.
  2. Read carefully BUILDING.txt.
  3. Installed dependencies:
    3a) Windows SDK 7.1
    3b) Maven (I used 3.0.5)3c) JDK (I used 1.7.25)
    3d) ProtocolBuffer (I used 2.5.0 - http://protobuf.googlecode.com/files/protoc-2.5.0-win32.zip). It is enough just to put compiler (protoc.exe) into some of the PATH folders.
    3e) A set of UNIX command line tools (I installed Cygwin)
  4. Started command line of Windows SDK. Start All programs Microsoft Windows SDK v7.1 .. Command Prompt (I modified this shortcut, adding option /release in the command line to build release versions of native code). All the next steps are made from inside SDK command line window)
  5. Set up the environment:

    set JAVA_HOME={path_to_JDK_root}

It seems that JAVA_HOME MUST NOT contain space!

  1. Changed dir to sources root folder (BUILDING.txt warns that there are some limitations on the path length so sources root should have short name - I used D:hds)
  2. Ran building process:

    mvn package -Pdist -DskipTests

You can try without 'skipTests' but on my machine some tests failed and building was terminated. It may be connected to sybolic link issues mentioned in BUILDING .txt.8. Picked the result in hadoop-disttargethadoop-2.1.0-beta (windows executables and dlls are in 'bin' folder)

Winutils.exe Hadoop Download

I have followed following steps to install Hadoop 2.2.0

Steps to build Hadoop bin distribution for Windows

  1. Download and install Microsoft Windows SDK v7.1.

  2. Download and install Unix command-line tool Cygwin.

  3. Download and install Maven 3.1.1.

  4. Download Protocol Buffers 2.5.0 and extract to a folder (say c:protobuf).

  5. Add Environment Variables JAVA_HOME, M2_HOME and Platform if not added already. Note : Variable name Platform is case sensitive. And value will be either x64 or Win32 for building on a 64-bit or 32-bit system. Edit Path Variable to add bin directory of Cygwin (say C:cygwin64bin), bin directory of Maven (say C:mavenbin) and installation path of Protocol Buffers (say c:protobuf).

  6. Download hadoop-2.2.0-src.tar.gz and extract to a folder having short path (say c:hdfs) to avoid runtime problem due to maximum path length limitation in Windows.

  7. Select Start --> All Programs --> Microsoft Windows SDK v7.1 and open Windows SDK 7.1 Command Prompt. Change directory to Hadoop source code folder (c:hdfs). Execute mvn package with options -Pdist,native-win -DskipTests -Dtar to create Windows binary tar distribution.

  8. If everything goes well in the previous step, then native distribution hadoop-2.2.0.tar.gz will be created inside C:hdfshadoop-disttargethadoop-2.2.0 directory.

Install Hadoop

  1. Extract hadoop-2.2.0.tar.gz to a folder (say c:hadoop).

  2. Add Environment Variable HADOOP_HOME and edit Path Variable to add bin directory of HADOOP_HOME (say C:hadoopbin).

Configure Hadoop

C:hadoopetchadoopcore-site.xml

C:hadoopetchadoophdfs-site.xml

C:hadoopetchadoopmapred-site.xml

C:hadoopetchadoop yarn-site.xml

Format namenode

For the first time only, namenode needs to be formatted.

Start HDFS (Namenode and Datanode)

Start MapReduce aka YARN (Resource Manager and Node Manager)

Total four separate Command Prompt windows will be opened automatically to run Namenode, Datanode, Resource Manager, Node Manager

Reference : Build, Install, Configure and Run Apache Hadoop 2.2.0 in Microsoft Windows OS

I had the same problem but with recent hadoop v. 2.2.0. Here are my steps for solving that problem:

  1. I've built winutils.exe from sources. Project directory:

    hadoop-2.2.0-srchadoop-common-projecthadoop-commonsrcmainwinutils

    My OS: Windows 7. Tool for building: MS Visual Studio Express 2013 for Windows Desktop (it's free and can be loaded from http://www.microsoft.com/visualstudio/).Open Studio, File -> Open -> winutils.sln. Right click on solution on the right side ->Build.There were a couple errors in my case (you might need to fix project properties, specify output folder).Viola! You get winutils.exe - put it into hadoop's bin.

  2. Next we need to build hadoop.dll.Some woodoo magic here goes: open

    hadoop-2.2.0-srchadoop-common-projecthadoop-commonsrcmainnativenative.sln

    in MS VS; right click on solution -> build.I got a bunch of errors. I created manually several missed header files (don't ask me why they are missed in source tarball!):

    (and don't ask me what this project on git is for! I don't know - google pointed it out by searching header file names)I've copied

    hadoop-2.2.0-srchadoop-common-projecthadoop-commontargetwinutilsDebuglibwinutils.lib

    (result of step # 1) into

    hadoop-2.2.0-srchadoop-common-projecthadoop-commontargetbin

    And finally build operation produces hadoop.dll!Put it again into hadoop's bin and happily run namenode!

Hope my steps will help somebody.

Aleksei EgorovAleksei Egorov

Han has prepared the Hadoop 2.2 Windows x64 binaries (see his blog) and uploaded them to Github.

After putting the two binaries winutils.exe and hadoop.dll into the %hadoop_prefix%bin folder, I got the same UnsatisfiedLinkError.

The problem was that some dependency of hadoop.dll was missing. I used Dependency Walker to check the dependencies of the binaries and the Microsoft Visual C++ 2010 Redistributables were missing.

Winutils 64 Bit

So besides building all the components yourself, the answer to the problem is

  • make sure to use the same architecture for Java and the native code. java -version tells you if you use 32 or x64.
  • then use Dependency Walker to make sure all native binaries are pure and of the same architecture. Sometimes a x64 dependency is missing and Windows falls back to x86, which does not work. See answer of another question.
  • also check if all dependencies of the native binaries are satisfied.

In addition to other solutions, here is a pre-built copy of winutil.exe. Donload it and add to $HADOOP_HOME/bin. It works for me.

(Source :Click here)

Please add hadoop.dll (version sensitive) to the system32 directory under Windows Directory.

You can get the hadoop.dll at winutils

Instead of using the official branch I would suggest the windows optimized

You need to compile it, build winutils.exe under windows and place it in the hadoop/bin directory

Hadoop Download Windows 7

You might need to copy hadoop.dll and winutils.exe files from hadoop-common-bin to %HADOOP_HOME%binAdd %HADOOP_HOME%/bin to your %PATH% variable.

You can download hadoop-common from https://github.com/amihalik/hadoop-common-2.6.0-bin

I ran into same problem with Hadoop 2.4.1 on Windows 8.1; there were a few differences with the resulting solution caused mostly by the newer OS.

I first installed Hadoop 2.4.1 binary, unpacking it into %HADOOP_HOME%.

The previous answers describe how to set up Java, protobuf, cygwin, and maven, and the needed environment variables. I had to change my Platform environment variable from HP's odd 'BCD' value.

I downloaded the source from an Apache mirror, and unpacked it in a short directory (HADOOP_SRC = C:hsrc). Maven ran fine from a standard Windows command prompt in that directory: mvn package -DskipTests.

Instead of using the Windows 7 SDK (which I could not get to load) or the Windows 8.1 SDK (which doesn't have the command line build tools), I used the free Microsoft Visual Studio Express 2013 for Windows Desktop. Hadoop's build needed the MSBuild location (C:Program Files (x86)MSBuild12.0) in the PATH, and required that the various Hadoop native source projects be upgraded to the newer (MS VS 2013) format. The maven build failures were nice enough to point out the absolute path of each project as it failed, making it easy to load the project into Visual Studio (which automatically converts, after asking).

Once built, I copied the native executables and libraries into the Hadoop bin directory. They were built in %HADOOP_SRC%hadoop-common-projecthadoop-commontargetbin, and needed to be copied into %HADOOP_HOME%bin.

Adding hadoop.dll and hdfs.dll to the %HADOOP_HOME%bin folder did the trick for me.

Download & Install Java in c:/java/

make sure the path is this way, if java is installed in 'program files', then hadoop-env.cmd will not recognize java path

Download Hadoop binary distribution.

I am using binary distribution Hadoop-2.8.1. Also I would recommend to keep extraction path as short as possible

Set Environment Variables:

Hadoop will work on windows if Hadoop-src is built using maven in your windows machine. Building the Hadoop-src(distribution) will create a Hadoop binary distribution, which will work as windows native version.

But if you don't want to do that, then download pre-builted winutils of Hadoop distribution.Here is a GitHub link, which has winutils of some versions of Hadoop.

if the version you are using is not in the list, the follow the conventional method for setting up Hadoop on windows - link

If you found your version, then copy paste all content of folder into path: /bin/

Set all the .xml configuration files - Link & set JAVA_HOME path in hadoop-env.cmd file

From cmd go to:

Hope this helps.

This detailed step-by-step guide shows you how to install the latest Hadoop v3.3.0 on Windows 10. It leverages Hadoop 3.3.0 winutils tool. WLS (Windows Subsystem for Linux) is not required. This version was released on July 14 2020. It is the first release of Apache Hadoop 3.3 line. There are significant changes compared with Hadoop 3.2.0, such as Java 11 runtime support, protobuf upgrade to 3.7.1, scheduling of opportunistic containers, non-volatile SCM support in HDFS cache directives, etc.

Please follow all the instructions carefully. Once you complete the steps, you will have a shiny pseudo-distributed single node Hadoop to work with.

References

Refer to the following articles if you prefer to install other versions of Hadoop or if you want to configure a multi-node cluster or using WSL.

  • Install Hadoop 3.3.0 on Windows 10 using WSL (Windows Subsystems for Linux is requried)

Required tools

Before you start, make sure you have these following tools enabled in Windows 10.

ToolComments
PowerShell

We will use this tool to download package.

In my system, PowerShell version table is listed below:

Git Bash or 7 Zip

We will use Git Bash or 7 Zip to unzip Hadoop binary package.

You can choose to install either tool or any other tool as long as it can unzip *.tar.gz files on Windows.

Command PromptWe will use it to start Hadoop daemons and run some commands as part of the installation process.
Java JDK

JDK is required to run Hadoop as the framework is built using Java.

In my system, my JDK version is jdk1.8.0_161.

Check out the supported JDK version on the following page.

From Hadoop 3.3.0, Java 11 runtime is now supported.

Now we will start the installation process.

Step 1 - Download Hadoop binary package

Select download mirror link

Go to download page of the official website:

And then choose one of the mirror link. The page lists the mirrors closest to you based on your location. For me, I am choosing the following mirror link:

info In the following sections, this URL will be used to download the package. Your URL might be different from mine and you can replace the link accordingly.

Download the package

info In this guide, I am installing Hadoop in folder big-data of my F drive (F:big-data). If you prefer to install on another drive, please remember to change the path accordingly in the following command lines. This directory is also called destination directory in the following sections.

Open PowerShell and then run the following command lines one by one:

It may take a few minutes to download.


Once the download completes, you can verify it:

You can also directly download the package through your web browser and save it to the destination directory.

warning Please keep this PowerShell window open as we will use some variables in this session in the following steps. If you already closed it, it is okay, just remember to reinitialise the above variables: $client, $dest_dir.

Step 2 - Unpack the package

Now we need to unpack the downloaded package using GUI tool (like 7 Zip) or command line. For me, I will use git bash to unpack it.

Open git bash and change the directory to the destination folder:

And then run the following command to unzip:

The command will take quite a few minutes as there are numerous files included and the latest version introduced many new features.

After the unzip command is completed, a new folder hadoop-3.3.0 is created under the destination folder.


info When running the command you may experience errors like the following:
Please ignore it for now.

Step 3 - Install Hadoop native IO binary

Hadoop on Linux includes optional Native IO support. However Native IO is mandatory on Windows and without it you will not be able to get your installation working. The Windows native IO libraries are not included as part of Apache Hadoop release. Thus we need to build and install it.

infoThe following repository already pre-built Hadoop Windows native libraries:
https://github.com/kontext-tech/winutils
warning These libraries are not signed and there is no guarantee that it is 100% safe. We use it purely for test&learn purpose.

Download all the files in the following location and save them to the bin folder under Hadoop folder. For my environment, the full path is: F:big-datahadoop-3.3.0bin. Remember to change it to your own path accordingly.

Alternatively, you can run the following commands in the previous PowerShell window to download:

After this, the bin folder looks like the following:

Step 4 - (Optional) Java JDK installation

Java JDK is required to run Hadoop. If you have not installed Java JDK, please install it.

You can install JDK 8 from the following page:

Once you complete the installation, please run the following command in PowerShell or Git Bash to verify:

If you got error about 'cannot find java command or executable'. Don't worry we will resolve this in the following step.

Step 5 - Configure environment variables

Now we've downloaded and unpacked all the artefacts we need to configure two important environment variables.

Configure JAVA_HOME environment variable

As mentioned earlier, Hadoop requires Java and we need to configure JAVA_HOME environment variable (though it is not mandatory but I recommend it).

First, we need to find out the location of Java SDK. In my system, the path is: D:Javajdk1.8.0_161.

Your location can be different depends on where you install your JDK.

And then run the following command in the previous PowerShell window:

Remember to quote the path especially if you have spaces in your JDK path.

infoYou can setup environment variable at system level by adding option /M however just in case you don't have access to change system variables, you can just set it up at user level.

The output looks like the following:

Configure HADOOP_HOME environment variable

Similarly we need to create a new environment variable for HADOOP_HOME using the following command. The path should be your extracted Hadoop folder. For my environment it is: F:big-datahadoop-3.3.0.

If you used PowerShell to download and if the window is still open, you can simply run the following command:

The output looks like the following screenshot:


Alternatively, you can specify the full path:

Now you can also verify the two environment variables in the system:


Configure PATH environment variable

Once we finish setting up the above two environment variables, we need to add the bin folders to the PATH environment variable.

If PATH environment exists in your system, you can also manually add the following two paths to it:

  • %JAVA_HOME%/bin
  • %HADOOP_HOME%/bin

Alternatively, you can run the following command to add them:

If you don't have other user variables setup in the system, you can also directly add a Path environment variable that references others to make it short:

Close PowerShell window and open a new one and type winutils.exe directly to verify that our above steps are completed successfully:


You should also be able to run the following command:

Winutils.exe Hadoop 2.7

Step 6 - Configure Hadoop

Now we are ready to configure the most important part - Hadoop configurations which involves Core, YARN, MapReduce, HDFS configurations.

Configure core site

Edit file core-site.xml in %HADOOP_HOME%etchadoop folder. For my environment, the actual path is F:big-datahadoop-3.3.0etchadoop.

Replace configuration element with the following:

Configure HDFS

Edit file hdfs-site.xml in %HADOOP_HOME%etchadoop folder.

Before editing, please correct two folders in your system: one for namenode directory and another for data directory. For my system, I created the following two sub folders:

  • F:big-datadatadfsnamespace_logs_330
  • F:big-datadatadfsdata_330

Replace configuration element with the following (remember to replace the highlighted paths accordingly):

In Hadoop 3, the property names are slightly different from previous version. Refer to the following official documentation to learn more about the configuration properties:

infoFor DFS replication we configure it as one as we are configuring just one single node. By default the value is 3.
infoThe directory configuration are not mandatory and by default it will use Hadoop temporary folder. For our tutorial purpose, I would recommend customise the values.

Configure MapReduce and YARN site

Edit file mapred-site.xml in %HADOOP_HOME%etchadoop folder.

Replace configuration element with the following:

Edit fileyarn-site.xml in %HADOOP_HOME%etchadoop folder.

Step 7 - Initialise HDFS & bug fix

Run the following command in Command Prompt

The following is an example when it is formatted successfully:


Step 8 - Start HDFS daemons

Run the following command to start HDFS daemons in Command Prompt:

Two Command Prompt windows will open: one for datanode and another for namenode as the following screenshot shows:

Verify HDFS web portal UI through this link: http://localhost:9870/dfshealth.html#tab-overview.

You can also navigate to a data node UI:


Step 9 - Start YARN daemons

warning You may encounter permission issues if you start YARN daemons using normal user. To ensure you don't encounter any issues. Please open a Command Prompt window using Run as administrator.
Alternatively, you can follow this comment on this page which doesn't require Administrator permission using a local Windows account:
https://kontext.tech/column/hadoop/377/latest-hadoop-321-installation-on-windows-10-step-by-step-guide#comment314

Run the following command in an elevated Command Prompt window (Run as administrator) to start YARN daemons:

Similarly two Command Prompt windows will open: one for resource manager and another for node manager as the following screenshot shows:


You can verify YARN resource manager UI when all services are started successfully.
