New in this Release

This is the initial release of Hive 1.0 for the MapR distribution for Hadoop. In addition to Hive 1.0 features, this release includes the following features:

  • MapR-SASL Support

    On secure MapR clusters, MapR-SASL is supported and configured by default for HiveServer2 and HiveMetastore. Previously, Simple SASL was the default and authentication had to be configured manually.

  • Hive Scratch Directory Changes

    By default, the Hive scratch directory is created in the same volume as the target table (hive.optimize.insert.dest.volume=true). Previously, hive.optimize.insert.dest.volume was set to false.

  • WebHCat Changes
    • The default WebHCat log directory is now /opt/mapr/hive/<hive-version>/logs/<username>/webhcat. Previously, it was /tmp/<username>/webhcat.
    • WebHCat is now managed by Warden. The warden.hcat.conf file is installed with the mapr-hive package.
  • JDBC SASL QOP Parameter Changes

    When you need to connect via JDBC to hiveserver2 using the SASL QOP parameter, use salsQop instead of sals.qop.

Important: The Hive 1.0 cost-based optimization is a beta feature and is not fully supported.
