Winutils Exe Hadoop
2021年10月10日Download here: http://gg.gg/w6auj
Winutils.exe hadoop.dll and hdfs.dll binaries for hadoop windows - cdarlint/winutils. However winutils.exe is a tool created to help if you don’t plan to use Hadoop in order to perform distrubite computing, for example because you are only testing Spark locally, on Windows. Press WIN+PAUSE, go to Advanced Settings and Environment variables. Set HADOOPHOME and PATH – In your environment variables either using Control Panel ( available to all apps – recommended option) or on command prompt ( for the current session) – set HADOOPHOME as C:/hadoop or the path inside which you created bin directory where winutils.exe is present.
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.warning Without consent from author, please don’t redistribute any part of the content on this page.

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.ToolCommentsPowerShell
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 packageSelect 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 packageinfo 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/winutilswarning 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:Failed To Locate The Winutils Binary In The Hadoop Binary ...
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: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 daemonswarning 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.
Step 10 - Verify Java processes
Run the following command to verify all running processes:
The output looks like the following screenshot:
* We can see the process ID of each Java process for HDFS/YARN.
Step 11 - Shutdown YARN & HDFS daemons
You don’t need to keep the services running all the time. You can stop them by running the following commands one by one once you finish the test:check Congratulations! You’ve successfully completed the installation of Hadoop 3.3.0 on Windows 10.
Let me know if you encounter any issues. Enjoy with your latest Hadoop on Windows 10.Apache Spark
