New in this Release

This release of Apache Hive includes the following behavior change that is specific to MapR:
Flexible HiveServer2 Authentication Support
When the cluster is secure, HiveServer2 accepts both MAPR-SASL and PAM for in-bound authentication. This allows a single instance of HiveServer2 to accept both MapR-SASL authentication from Hue and PAM authentication from JDBC/ODBC connections.

For details on the features available in the open source version of this component, see the Apache Hive 1.2.1 changelog or the Apache Hive homepage.
