Source Code for HPE Ezmeral Data Fabric Software

HPE regularly releases updates to Apache Hadoop ecosystem projects as the projects are released by Apache, after HPE can verify that the changes do not impact product stability. Releases of ecosystem components are independent of the release cycle for the core data-fabric software, so that new updates can be released quickly and efficiently.

Source code developed by HPE can be found on GitHub at http://github.com/mapr as of March 2013, coincident with version 2.1.2 of the data-fabric distribution. HPE may also release source code for other data-fabric projects at github.com/mapr. For each release that HPE includes in its distribution, HPE branches and tags the release on GitHub using the underlying project release number appended by -mapr.

Finding Source Changes Prior to February 2013

GitHub is the single, central location for tracking changes that HPE applies to components in releases of the data-fabric distribution. Prior to February 2013, HPE included a list of patches in each component directory, as shown below. This information is no longer stored in the installation directory for recent releases, and instead is available at GitHub.
