What are Spark jobs?

In a Spark application, when you invoke an action on RDD, a job is created. Jobs are the main function that has to be done and is submitted to Spark. The jobs are divided into stages depending on how they can be separately carried out (mainly on shuffle boundaries). Then, these stages are divided into tasks.

What can you do with Spark?
