The spark-submit script in Spark’s bin directory is used to launch applications on a cluster. It can use all of Spark’s supported cluster managers through a uniform interface so you don’t have to configure your application especially for each one.

The Spark Java API exposes all the Spark features available in the Scala version to Java. To learn the basics of Spark, we recommend reading through the Scala programming guide first; it should be easy to follow even if you don’t know Scala.

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.

Spark standalone and YARN only: (Default: 1 in YARN mode, or all available cores on the worker in standalone mode) YARN only: --queue QUEUE_NAME The YARN queue to submit to. The most common way to launch spark applications on the cluster is to use the shell command spark-submit. When using spark-submit shell command the spark application need not be configured particularly for each cluster as the spark-submit shell script uses the cluster managers through a single interface. Use spark-submit to run our code. We need to specify the main class, the jar to run, and the run mode (local or cluster): spark-submit --class "Hortonworks.SparkTutorial.Main" --master local ./SparkTutorial-1.0-SNAPSHOT.jar.

Apache Spark Examples. These examples give a quick overview of the Spark API. Spark is built on the concept of distributed datasets, which contain arbitrary Java or Python objects. You create a dataset from external data, then apply parallel operations to it. The building block of the Spark API is its RDD API.

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.
