Setting up Apache Spark on Linux Server
Before jumping into big data processing with Apache Spark on Linux Server, you need to set up Spark on your Linux machine. Here are the steps to install and configure Apache Spark on a Linux Server:
Step 1: Install Java
Spark requires Java to run, so make sure you have Java installed on your Linux machine. You can install Java using the following command:
sudo apt-get install default-jdk
Step 2: Download and Install Spark
You can download the latest version of Apache Spark from the official website. Once downloaded, extract the Spark tarball to a suitable location by using the following command:
tar -xvf spark-3.0.2-bin-hadoop3.2.tgz
After extracting the tarball, move the Spark directory to a suitable location:
sudo mv spark-3.0.2-bin-hadoop3.2 /opt/spark
Step 3: Export Spark’s Environment Variables
Next, you need to add the following lines to your .bashrc
file to set Spark’s environment variables:
export SPARK_HOME=/opt/spark
export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin
Step 4: Spark Configuration
Finally, you need to configure Spark according to your requirements. Spark’s configuration is stored in the conf/
directory in the Spark installation directory. You can modify different configuration files such as spark-env.sh
, spark-defaults.conf
, and log4j.properties
to customize Spark’s behavior.
