6.0 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.
- Application Development Process
  Before you start developing applications on MapR’s Converged Data Platform, consider how you will get the data onto the platform, the format it will be stored in, the type of processing or modeling that is required, and how the data will be accessed.
- MapR-FS and Apps
  The following sections provide information about accessing MapR-FS with C and Java applications.
- MapR-DB and Apps
  This section contains information about developing client applications for JSON and binary tables.
- MapR-ES and Apps
  MapR-ES brings integrated publish and subscribe messaging to the MapR Converged Data Platform.
- MapReduce and Apps
  This section contains information associated with developing YARN applications.
- MapR Data Science Refinery
  The MapR Data Science Refinery is an easy-to-deploy and scalable data science toolkit with native access to all platform assets and superior out-of-the-box security.
- MapR Data Fabric for Kubernetes FlexVolume Driver
  This section describes how to use and troubleshoot the MapR Data Fabric for Kubernetes FlexVolume Driver.
- Ecosystem Components
  The following sections provide information about each open source project that MapR supports.
  - MapR Ecosystem Packs
    A MapR Ecosystem 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.
  - AsyncHBase
    - Compiling and Running AsyncHBase Applications
      When you compile or run AsyncHBase applications, you need to include the required AsyncHBase libraries.
    - AsyncHBase Script
      MapR provides an AsyncHBase script that you can use to run applications and generate the AsyncHBase classpath.
    - AsyncHBase Behavior with MapR-DB Binary Tables
      After you install AsyncHBase, you can use the AsyncHBase libraries to provide asynchronous access to MapR-DB binary tables. However, it is important to note the behavior that is specific to using AsyncHBase with MapR-DB.
    - Using OpenTSDB with AsyncHBase
      OpenTSDB can use MapR’s AsyncHBase to perform time-series data-plots on MapR-DB binary tables.
    - GetRequest API
      MapR includes an additional constructor for the GetRequest class which takes an extra qualifier.

  This section contains in-depth information for the developer.
- API Documentation
  MapR supports public APIs for MapR-FS, MapR-DB, and MapR-ES. These APIs are available for application development purposes.

AsyncHBase

MapR provides a version of AsyncHBase that is modified to work with MapR-DB binary tables. The MapR version of AsyncHBase is based on the AsyncHBase library provides asynchronous Java APIs to access MapR-DB binary tables. The HBase Client version is based on the current MEP and MapR version you are running. For more information, see the Interoperability Matrices.
