Chapter 1. Analyzing Data with Apache Spark
Hortonworks Data Platform (HDP) supports Apache Spark, a fast, large-scale data processing engine.
Deep integration of Spark with YARN allows Spark to operate as a cluster tenant alongside Apache engines such as Hive, Storm, and HBase, all running simultaneously on a single data platform. Instead of creating and managing a set of dedicated clusters for Spark applications, you can store data in a single location, access and analyze it with multiple processing engines, and leverage your resources.
Spark on YARN leverages YARN services for resource allocation, runs Spark executors in YARN containers, and supports workload management and Kerberos security features. It has two modes:
YARN-cluster mode, optimized for long-running production jobs
YARN-client mode, best for interactive use such as prototyping, testing, and debugging
Spark shell and the Spark Thrift server run in YARN-client mode only.
