Apache Kafka Integration With Spark

1. Introduction

This is an in-depth article related to Apache Kafka and Spark Integration. Apache Kafka is an Apache open-source project. It was initially created on Linkedin. Kafka framework was created in java and scala. It supports publish-subscribe messaging and is fault-tolerant. It is scalable and performs for high-volume messaging. Zookeeper is the basic component that manages the Apache Kafka Server. Kafka has features related to reliability, scalability, performance, distributed logging, and durability. Spark is used for big data processing and executing machine learning algorithms.

2. Apache Kafka – Spark Integration

2.1 Prerequisites

Java 7 or 8 is required on the linux, windows or mac operating system. Maven 3.6.1 is required for building the kafka and spark application.

2.2 Download

You can download Java 8 can be downloaded from the Oracle web site . Apache Maven 3.6.1 can be downloaded from Apache site. Kafka framework’s latest releases are available from this website.

2.3 Setup

You can set the environment variables for JAVA_HOME and PATH. They can be set as shown below:

Setup
JAVA_HOME="/desktop/jdk1.8.0_73"
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH

The environment variables for maven are set as below:

Maven Environment
JAVA_HOME=”/jboss/jdk1.8.0_73″
export M2_HOME=/users/bhagvan.kommadi/Desktop/apache-maven-3.6.1
export M2=$M2_HOME/bin
export PATH=$M2:$PATH

2.4 How to download and install Apache Kafka

Apache Kafka’s latest releases are available from the apache Kafka website. After downloading the zip file can be extracted to a folder.

To start the zookeeper, you can use the command below:

Zoo keeper
bin/zookeeper-server-start.sh config/zookeeper.properties

The output of the above command is shown as below:

You can now start the apache kafka server using the command below:

Apache Kafka Server Run Command
bin/kafka-server-start.sh config/server.properties

The output of the above command is shown as below:

2.5 Spark Integration Example

Apache Spark is based on Hadoop and its key components HDFS and YARN. Spark release consists of Hadoop packages. Let us look at an example that shows the Spark and Kafka integration. Topics are configured on Kafka. Spark connects to Kafka’s topic to receive a stream of messages. Messages can be processed in real-time. The source code is shown below for the example.

		try {
			kafkaStreamingContext.awaitTermination();
		} catch (InterruptedException exception) {

			exception.printStackTrace();

The command for executing the example is shown below:

Execution Command
 mvn exec:java -Dexec.mainClass=KafkaSparkIntegrationExample 

You can create a topic by using this command :

Kafka producer CLI
./bin/kafka-topics.sh --create   --zookeeper localhost:2181   --replication-factor 1 --partitions 1   --topic new_topic

The output of the above CLI command is shown as below:
