What is spark SQL?
Spark SQL is a Spark module for structured data processing. It provides a programming abstraction called DataFrames and can also act as a distributed SQL query engine. It enables unmodified Hadoop Hive queries to run up to 100x faster on existing deployments and data.
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?
Spark is a general-purpose distributed data processing engine that is suitable for use in a wide range of circumstances. On top of the Spark core data processing engine, there are libraries for SQL, machine learning, graph computation, and stream processing, which can be used together in an application.
How do I run Spark-submit?
You can submit a Spark batch application by using cluster mode (default) or client mode either inside the cluster or from an external client: Cluster mode (default): Submitting Spark batch application and having the driver run on a host in your driver resource group.
