Apache Spark is a general framework for distributed computing that offers high performance for both batch and interactive processing.
To run applications distributed across a cluster, Spark requires a cluster manager. In CDH 6, Cloudera supports only the YARN cluster manager. When run on YARN, Spark application processes are managed by the YARN ResourceManager and NodeManager roles. Spark Standalone is no longer supported.
