Release Notes

CDAP Bug Fixes

  • Fixed a problem with a Coopr-provisioned secure cluster failing to start due to a classpath issue CDAP-478.
  • Fixed a problem with the WISE app zip distribution not packaged correctly; a new version (0.2.1) has been released CDAP-533.
  • Fixed a problem with the examples and tests incorrectly using the ByteBuffer.array method when reading a Stream event CDAP-549.
  • Fixed a problem with the Authentication Server so that it can now communicate with an LDAP instance over SSL CDAP-556.

Other Changes

    • Re-organized the documentation into three manuals—Developers’ Manual, Administration Manual, Reference Manual—and a set of examples, how-to guides and tutorials;
    • Documents are now in smaller chapters, with numerous updates and revisions;
    • Added a link for downloading an archive of the documentation for offline use;
    • Added links to examples relevant to a particular component;
    • Added suggested deployment architectures for Distributed CDAP installations;
    • Added a glossary;
    • Added navigation aids at the bottom of each page; and
    • Tested and updated the Standalone CDAP examples and their documentation.

Known Issues

  • Currently, applications that include Spark or Scala classes in user classes not extended from either JavaSparkProgram or ScalaSparkProgram (depending upon the language) fail with a class loading error. Spark or Scala classes should not be used outside of the Spark program. CDAP-599
