This guide will show you how to install Apache Spark on Windows 10 and test the installation.
- A system running Windows 10
- A user account with administrator privileges (required to install software, modify file permissions, and modify system PATH)
- Command Prompt or Powershell
- A tool to extract .tar files, such as 7-Zip
Installing Apache Spark on Windows 10 may seem complicated to novice users, but this simple tutorial will have you up and running. If you already have Java 8 and Python 3 installed, you can skip the first two steps.
- 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: winutils bin winutils.exe. Now, open environment variable and set HADOOPHOME=C: winutils NOTE: Please do not add bin in HADOOPHOME and no need to set HADOOP.
- HADOOP-11003 org.apache.hadoop.util.Shell should not take a dependency on binaries being deployed when used as a library.
Apache Spark requires Java 8. You can check to see if Java is installed using the command prompt.
Open the command line by clicking Start > type cmd > click Command Prompt.
Type the following command in the command prompt:

12. When the installation completes, click the Disable path length limit option at the bottom and then click Close.
13. If you have a command prompt open, restart it. Keygen wiso sparbuch 2013 corvette. Verify the installation by checking the version of Python:
The output should print
Python 3.8.3
.Note: For detailed instructions on how to install Python 3 on Windows or how to troubleshoot potential issues, refer to our Install Python 3 on Windows guide.
1. Open a browser and navigate to https://spark.apache.org/downloads.html.
2. Under the Download Apache Spark heading, there are two drop-down menus. Use the current non-preview version.
- In our case, in Choose a Spark release drop-down menu select 2.4.5 (Feb 05 2020).
- In the second drop-down Choose a package type, leave the selection Pre-built for Apache Hadoop 2.7.
3. Click the spark-2.4.5-bin-hadoop2.7.tgz link.
4. A page with a list of mirrors loads where you can see different servers to download from. Pick any from the list and save the file to your Downloads folder.
1. Verify the integrity of your download by checking the checksum of the file. This ensures you are working with unaltered, uncorrupted software.
2. Navigate back to the Spark Download page and open the Checksum link, preferably in a new tab.
3. Next, open a command line and enter the following command:
4. Change the username to your username. The system displays a long alphanumeric code, along with the message
Certutil: -hashfile completed successfully
.5. Compare the code to the one you opened in a new browser tab. If they match, your download file is uncorrupted.
Installing Apache Spark involves extracting the downloaded file to the desired location.
1. Create a new folder named Spark in the root of your C: drive. From a command line, enter the following:
2. In Explorer, locate the Spark file you downloaded.
3. Right-click the file and extract it to C:Spark using the tool you have on your system (e.g., 7-Zip). Una cuestion de confianza radclyffe pdf editor.
4. Now, your C:Spark folder has a new folder spark-2.4.5-bin-hadoop2.7 with the necessary files inside.
Download the winutils.exe file for the underlying Hadoop version for the Spark installation you downloaded.
1. Navigate to this URL https://github.com/cdarlint/winutils and inside the bin folder, locate winutils.exe, and click it.
2. Find the Download button on the right side to download the file.
3. Now, create new folders Hadoopand bin on C: using Windows Explorer or the Command Prompt.
4. Copy the winutils.exe file from the Downloads folder to C:hadoopbin.
This step adds the Spark and Hadoop locations to your system PATH. It allows you to run the Spark shell directly from a command prompt window.
1. Click Start and type environment.
2. Select the result labeled Edit the system environment variables.
3. A System Properties dialog box appears. In the lower-right corner, click Environment Variables and then click New in the next window.
4. For Variable Name type SPARK_HOME.
5. For Variable Value type C:Sparkspark-2.4.5-bin-hadoop2.7 and click OK. If you changed the folder path, use that one instead.
6. In the top box, click the Path entry, then click Edit. Be careful with editing the system path. Avoid deleting any entries already on the list.
7. You should see a box with entries on the left. On the right, click New.
8. The system highlights a new line. Enter the path to the Spark folder C:Sparkspark-2.4.5-bin-hadoop2.7bin. We recommend using %SPARK_HOME%bin to avoid possible issues with the path.
9. Repeat this process for Hadoop and Java.
- For Hadoop, the variable name is HADOOP_HOME and for the value use the path of the folder you created earlier: C:hadoop. Add C:hadoopbin to the Path variable field, but we recommend using %HADOOP_HOME%bin.
- For Java, the variable name is JAVA_HOME and for the value use the path to your Java JDK directory (in our case it’s C:Program FilesJavajdk1.8.0_251).
10. Click OK to close all open windows.
Note: Star by restarting the Command Prompt to apply changes. If that doesn't work, you will need to reboot the system.
1. Open a new command-prompt window using the right-click and Run as administrator:
2. To start Spark, enter:
If you set the environment path correctly, you can type
spark-shell
to launch Spark.3. The system should display several lines indicating the status of the application. You may get a Java pop-up. Select Allow access to continue.
Finally, the Spark logo appears, and the prompt displays the Scala shell.
4., Open a web browser and navigate to http://localhost:4040/.
5. You can replace localhost with the name of your system.
6. You should see an Apache Spark shell Web UI. The example below shows the Executors page.
7. To exit Spark and close the Scala shell, press
ctrl-d
in the command-prompt window.Note: If you installed Python, you can run Spark using Python with this command:
Exit using
quit()
. God of war 2 rom.In this example, we will launch the Spark shell and use Scala to read the contents of a file. You can use an existing file, such as the README file in the Spark directory, or you can create your own. We created pnaptest Os x version 10.7 5 for mac. with some text.
1. Open a command-prompt window and navigate to the folder with the file you want to use and launch the Spark shell.
2. First, state a variable to use in the Spark context with the name of the file. Remember to add the file extension if there is any.
3. The output shows an RDD is created. Then, we can view the file contents by using this command to call an action:
This command instructs Spark to print 11 lines from the file you specified. To perform an action on this file (value x), add another value y, and do a map transformation.
4. For example, you can print the characters in reverse with this command:
5. The system creates a child RDD in relation to the first one. Then, specify how many lines you want to print from the value y:
The output prints 11 lines of the pnaptest file in the reverse order.
When done, exit the shell using
ctrl-d
.You should now have a working installation of Apache Spark on Windows 10 with all dependencies installed. Get started running an instance of Spark in your Windows environment.
