5.2 Application Development
This section contains information related to application development for ecosystem components and MapR products including MapR-DB (binary and JSON), MapR-FS, and MapR Streams.
- Connecting to the Cluster
  Application are often run on nodes that are not part of the MapR Cluster. There are many methods to connect to a MapR cluster; this section will briefly describe each option.
- MapR-FS and Applications
  The following sections provide information about accessing MapR-FS with C and Java applications.
- MapR-DB and Applications
  This section contains information on developing client applications for binary and JSON tables.
- MapR Streams and Applications
  MapR Streams brings integrated publish/subscribe messaging to the MapR Converged Data Platform.
- MapReduce and Applications
  This section contains information associated with developing MapReduce programs or YARN applications.
- Ecosystem Components
  The following sections provide information about each open source project that MapR supports.
  - MapR Expansion Packs
    A MapR Expansion Pack (MEP) provides a set of ecosystem components that work together on one or more MapR cluster versions. Only one version of each ecosystem component is available in each MEP. For example, only one version of Hive and one version of Spark is supported in a MEP.

Mahout

The Apache Mahout™ machine learning library's goal is to build scalable machine learning libraries. For details about the algorithms available in Mahout, see the Apache Mahout website.

This documentation provides information about using Mahout with MapR, but it does not duplicate Apache documentation. For additional documentation, see the Apache Mahout website.
