Apache Spark Overview
Apache Spark is a distributed, in-memory data processing engine designed for large-scale data processing and analytics.
Apache Spark is a general framework for distributed computing that offers high performance for both batch and interactive processing. It exposes APIs for Java, Python, and Scala and consists of Spark core and several related projects.
You can run Spark applications locally or distributed across a cluster, either by using an interactive shell or by submitting an application. Running Spark applications interactively is commonly performed during the data-exploration phase and for ad hoc analysis.
To run applications distributed across a cluster, Spark requires a cluster manager. Cloudera Data Platform (CDP) 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 not supported.
For detailed API information, see the Apache Spark project site.
CDP supports Apache Spark, Apache Livy for local and remote access to Spark through the Livy REST API, and Apache Zeppelin for browser-based notebook access to Spark. The Spark LLAP connector is not supported.
