MapR 6.0 Documentation

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.

OpenStack Manila

The OpenStack Manila provides shared filesystems as a service. Developer documentation for OpenStack Manila project is available here.

The MapR manila file system driver enables manila to create and manage shares on the MapR file system, which is designed to hold very large amounts of data. The driver is a plug-in based on the Shared File Systems service and provides high-throughput access to the data on MapR-FS distributed file system.

A Shared File Systems service share in this driver is a volume in MapR file system. Instances talk directly to the MapR file system storage backend via the (mapr-posix) client. To mount a MapR file system volume, the MapR POSIX client is required. Access to each share is allowed by user and group based access type, which is aligned with MapR file system ACEs to support access control for multiple users and groups. If user name and group name are the same, the group access type will be used by default.

The MapR manila driver interacts with MapR-FS via the REST API. The MapR Manila driver is supported on Manila 1.5.0 and 1.8.1. For information on installing the:

OpenStack Manila, refer to the Installation Tutorial.
MapR Manila driver, see MapRFS Native Driver.

To use the manila shares created by MapR manila driver, you must first install and configure the POSIX (loopbacknfs or FUSE-based) client on the tenant hosts by following the steps for Setting Up a Tenant.
