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.
