New in this Release
This is the initial release of Hive 1.2.1 for the MapR distribution for Hadoop. In addition to Hive 1.2.1 features, this release includes the following behavior changes and features:
-
HiveServer2 Authentication
On secure MapR clusters, 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 enabled by default.
-
Hive ODBC Driver 2.1.8
For Hive 1.2.1, use Hive ODBC driver version 2.1.8 or above. This driver cannot be installed on CentOS 7.
Hive Feature Support
MapR does not support Hive on Spark. Therefore, you cannot use Spark as an execution engine for Hive. However, you can run Hive and Spark on the same cluster and you can use SparkQL to query Hive tables.
