Apache Spark is an open-source distributed computing system that provides an interface for programming entire clusters with implicit data parallelism and fault tolerance. In this guide, we will walk through the steps to install Apache Spark on Debian 11.

Step 1: Update Your System

Start by ensuring your system is up to date:

sudo apt update && sudo apt upgrade -y

Step 2: Install Java

Apache Spark requires Java to be installed. Install the OpenJDK package:

sudo apt install openjdk-11-jdk -y

Step 3: Verify Java Installation

Verify that Java is installed by checking its version:

java -version

Step 4: Download Apache Spark

Download the latest version of Apache Spark from the official website:

wget https://downloads.apache.org/spark/spark-3.2.3/spark-3.2.3-bin-hadoop3.2.tgz

Extract the downloaded archive:

tar -xzf spark-3.2.3-bin-hadoop3.2.tgz

Step 5: Move Spark to /opt Directory

Move the extracted directory to /opt:

sudo mv spark-3.2.3-bin-hadoop3.2 /opt/spark

Step 6: Set Up Environment Variables

Add the Spark binary directory to your PATH. Open your profile file:

sudo nano /etc/profile

Add the following lines to the end of the file:

export SPARK_HOME=/opt/spark
export PATH=$PATH:$SPARK_HOME/bin

Save and exit the editor. Then, load the new environment variables:

source /etc/profile

Step 7: Verify Spark Installation

Check if Spark is installed correctly by running:

spark-shell

You should see the Spark shell starting up.

Step 8: Running a Simple Spark Application

You can run a simple Spark application to test your installation. In the Spark shell, you can try the following command:

scala> val data = Seq(1, 2, 3, 4, 5)
scala> val rdd = sc.parallelize(data)
scala> rdd.reduce(_ + _)
