In this post I will show you how to submit a Spark job from Java code. Typically, we submit Spark jobs to "Spark Cluster" and Hadoop/YARN by using $SPARK_HOME/bin/spark-submit shell script. Submitting Spark job from a shell script limits programmers when they want to submit Spark jobs from Java code (such as Java servlets or other Java code such as REST servers). Use YARN's Client Class. Below is a complete Java code, which submits a Spark job to YARN from Java code (no shell scripting is ./bin/spark-submit \--master yarn \--deploy-mode cluster \ --executor-memory 5G \ --executor-cores 8 \--py-files dependency_files/egg.egg --archives dependencies.tar.gz mainPythonCode.py value1 value2 #This is the Main Python Spark code file followed by #arguments(value1,value2) passed to the program Submit the spark application using the following command − spark-submit --class SparkWordCount --master local wordcount.jar If it is executed successfully, then you will find the output given below.

For that, jars/libraries that are present in Apache Spark package are required. The path of these jars has to be included as dependencies for the Java Project. In this tutorial, we shall look into how to create a Java Project with Apache Spark having all the required jars and libraries. The name for the tool to submit spark application is the spark-submit. As the first parameter, we tell it about the spark master. We are using a local mode spark cluster, and hence the value is local.
