How to Install PySpark on Windows

In this article, I will explain how to install and run PySpark on windows and also explains how to start a history server and monitor your jobs using Web UI.

PySpark is a Spark library written in Python to run Python application using Apache Spark capabilities. so there is no PySpark library to download. All you need is Spark.

Follow the below steps to Install PySpark on Windows.

Install Python or Anaconda distribution

Download and install either Python from Python.org or Anaconda distribution which includes Python, Spyder IDE, and Jupyter notebook. I would recommend using Anaconda as it’s popular and used by the Machine Learning & Data science community.

Install Java 8

To run PySpark application, you would need Java 8 or later version hence download the Java version from Oracle and install it on your system.

Post installation, set JAVA_HOME and PATH variable.


JAVA_HOME = C:\Program Files\Java\jdk1.8.0_201
PATH = %PATH%;C:\Program Files\Java\jdk1.8.0_201\bin

PySpark Install on Windows

PySpark is a Spark library written in Python to run Python application using Apache Spark capabilities. so there is no PySpark library to download. All you need is Spark; follow the below steps to install PySpark on windows.

1. On Spark Download page, select the link “Download Spark (point 3)” to download. If you wanted to use a different version of Spark & Hadoop, select the one you wanted from drop-downs and the link on point 3 changes to the selected version and provides you with an updated link to download.

2. After download, untar the binary using 7zip and copy the underlying folder spark-3.0.0-bin-hadoop2.7 to c:\apps

3. Now set the following environment variables.


SPARK_HOME  = C:\apps\spark-3.0.0-bin-hadoop2.7
HADOOP_HOME = C:\apps\spark-3.0.0-bin-hadoop2.7
PATH=%PATH%;C:\apps\spark-3.0.0-bin-hadoop2.7\bin

Install winutils.exe on Windows

Download wunutils.exe file from winutils, and copy it to %SPARK_HOME%\bin folder. Winutils are different for each Hadoop version hence download the right version from https://github.com/steveloughran/winutils

PySpark shell

Now open command prompt and type pyspark command to run PySpark shell. You should see something like below.

Spark-shell also creates a Spark context web UI and by default, it can access from http://localhost:4041.

Web UI

Apache Spark provides a suite of Web UIs (Jobs, Stages, Tasks, Storage, Environment, Executors, and SQL) to monitor the status of your Spark application.

History Server

History servers, keep a log of all PySpark application you submit by spark-submit, pyspark shell. before you start, first you need to set the below config on spark-defaults.conf


spark.eventLog.enabled true
spark.history.fs.logDirectory file:///c:/logs/path

Now, start history server on Linux or mac by running.


$SPARK_HOME/sbin/start-history-server.sh

If you are running PySpark on windows, you can start the history server by starting the below command.


$SPARK_HOME/bin/spark-class.cmd org.apache.spark.deploy.history.HistoryServer

By default History server listens at 18080 port and you can access it from browser using http://localhost:18080/

By clicking on each App ID, you will get the details of the application in PySpark web UI.

Conclusion

In summary, you have learned how to install pyspark on windows and run sample statements in spark-shell

If you have any issues, setting up, please message me in the comments section, I will try to respond with the solution.

Happy Learning !!
