Chapter 3. Deep Dive into Apache Spark

Apache Spark is growing at a fast pace in terms of technology, community, and user base. Two new APIs were introduced in 2015: the DataFrame API and DataSet API. These two APIs are built on top of the core API, which is based on RDDs. It is essential to understand the deeper concepts of RDDs including runtime architecture and behavior on various resource managers of Spark.

This chapter is divided into the following sub topics:

• Starting Spark daemons
• Spark core concepts
• Pairing RDDs
• The lifecycle of a Spark program
• Spark applications
• Persistence and caching
• Spark resource managers—Standalone, Yarn, and Mesos
