How to Install and Setup Apache Spark on Ubuntu/Debian

30

Apache Spark is an open-source distributed computational framework that is created to provide faster computational results. It is an in-memory computational engine, meaning the data will be processed in memory.

Spark supports various APIs for streaming, graph processing, SQL, MLLib. It also supports Java, Python, Scala, and R as the preferred languages. Spark is mostly installed in Hadoop clusters but you can also install and configure spark in standalone mode.

In this article, we will be seeing how to install Apache Spark in Debian and Ubuntu-based distributions.

Install Java and Scala in Ubuntu

To install Apache Spark in Ubuntu, you need to have Java and Scala installed on your machine. Most of the modern distributions come with Java installed by default and you can verify it using the following command.

$ java -version
Check Java Version in Ubuntu

If no output, you can install Java using our article on how to install Java on Ubuntu or simply run the following commands to install Java on Ubuntu and Debian-based distributions.

$ sudo apt update
$ sudo apt install default-jre
$ java -version

Next, you can install Scala from the apt repository by running the following commands to search for scala and install it.

$ sudo apt search scala  ⇒ Search for the package
$ sudo apt install scala ⇒ Install the package

To verify the installation of Scala, run the following command.

$ scala -version

Install Apache Spark in Ubuntu

Now go to the official Apache Spark download page and grab the latest version (i.e. 3.1.1) at the time of writing this article. Alternatively, you can use the wget command to download the file directly in the terminal.

$ wget https://apachemirror.wuchna.com/spark/spark-3.1.1/spark-3.1.1-bin-hadoop2.7.tgz

Now open your terminal and switch to where your downloaded file is placed and run the following command to extract the Apache Spark tar file.

$ tar -xvzf spark-3.1.1-bin-hadoop2.7.tgz

Finally, move the extracted Spark directory to /opt directory.

$ sudo mv spark-3.1.1-bin-hadoop2.7 /opt/spark

Configure Environmental Variables for Spark

Now you have to set a few environmental variables in your .profile file before starting up the spark.

$ echo "export SPARK_HOME=/opt/spark" >> ~/.profile
$ echo "export PATH=$PATH:/opt/spark/bin:/opt/spark/sbin" >> ~/.profile
$ echo "export PYSPARK_PYTHON=/usr/bin/python3" >> ~/.profile

To make sure that these new environment variables are reachable within the shell and available to Apache Spark, it is also mandatory to run the following command to take recent changes into effect.

$ source ~/.profile

All the spark-related binaries to start and stop the services are under the sbin folder.

$ ls -l /opt/spark
Spark Binaries

Start Apache Spark in Ubuntu

Run the following command to start the Spark master service and slave service.

$ start-master.sh
$ start-workers.sh spark://localhost:7077
Start Spark Service
Start Spark Service

Once the service is started go to the browser and type the following URL access spark page. From the page, you can see my master and slave service is started.

http://localhost:8080/
OR
http://127.0.0.1:8080
