How To Install Apache Spark on CentOS 7

Install Apache Spark on CentOS 7

In this tutorial, we will show you how to install Apache Spark on CentOS 7 server. For those of you who didn’t know, Apache Spark is a fast and general-purpose cluster computing system. It provides high-level APIs in Java, Scala, and Python, and also an optimized engine that supports overall execution charts. It also supports a rich set of higher-level tools including Spark SQL for SQL and structured information processing, MLlib for machine learning, GraphX for graph processing, and Spark Streaming.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Apache Spark on the CentOS 7 server.

Install Apache Spark on CentOS 7

Step 1. First, let’s start by ensuring your system is up-to-date.

yum clean all
yum -y install epel-release
yum -y update

Step 2. Installing Java.

Installing java for requirement install apache-spark:

yum install java -y

Once installed, check the java version:

java -version

Step 3. Installing Scala.

Spark installs Scala during the installation process, so we just need to make sure that Java and Python are present:

wget http://www.scala-lang.org/files/archive/scala-2.10.1.tgz
tar xvf scala-2.10.1.tgz
sudo mv scala-2.10.1 /usr/lib
sudo ln -s /usr/lib/scala-2.10.1 /usr/lib/scala
export PATH=$PATH:/usr/lib/scala/bin

Once installed, check the scala version:

scala -version

Step 4. Installing Apache Spark.

Install Apache Spark using the following command:

wget http://www-eu.apache.org/dist/spark/spark-2.2.1/spark-2.2.1-bin-hadoop2.7.tgz
tar -xzf spark-2.2.1-bin-hadoop2.7.tgz
export SPARK_HOME=$HOME/spark-2.2.1-bin-hadoop2.7
export PATH=$PATH:$SPARK_HOME/bin

Setup some Environment variables before you start spark:

echo 'export PATH=$PATH:/usr/lib/scala/bin' >> .bash_profile
echo 'export SPARK_HOME=$HOME/spark-2.2.1-bin-hadoop2.6' >> .bash_profile
echo 'export PATH=$PATH:$SPARK_HOME/bin' >> .bash_profile

The standalone Spark cluster can be started manually i.e. executing the start script on each node, or simply using the available launch scripts. For testing we can run master and slave daemons on the same machine:

./sbin/start-master.sh

Step 5. Configure Firewall for Apache Spark.

firewall-cmd --permanent --zone=public --add-port=6066/tcp
firewall-cmd --permanent --zone=public --add-port=7077/tcp
firewall-cmd --permanent --zone=public --add-port=8080-8081/tcp
firewall-cmd --reload

Step 6. Accessing Apache Spark.

Apache Spark will be available on HTTP port 7077 by default. Open your favorite browser and navigate to http://yourdomain.com:7077 or http://your-server-ip:7077 and complete the required steps to finish the installation.
