New in this Release

This release of Hive 1.0 for the MapR distribution for Hadoop includes the following behavior changes:

  • HiveServer2 Authentication Changes (Available for MapR cluster version 4.1 and above)

    On secure MapR clusters, MapR-SASL is not longer the default for HiveServer2. Instead, HiveServer2 uses PAM by default.

  • WebHCat Changes

    The warden.hcat.conf file is no longer installed with mapr-hive package. Instead, it is installed with the mapr-hivewebhcat package.

  • Cost-based optimization

    Cost-based optimization is disabled by default. For information on how to enable this option, see the Apache Hive documentation.


This release by MapR includes the following fixes on the base Apache release. For complete details, refer to the commit log for this project in GitHub.
