Feature Support

  • MapR supports Hive-2.1.1 on Tez-0.8.4. For more information, see Tez 0.8.4-1803 (MEP 4.1.1 and MEP 5.0.0) Release Notes.
  • MapR does not support Hive on Spark, so you cannot use Spark as an execution engine for Hive. However, you can run Hive and Spark on the same cluster. You can also use Spark SQL and Drill to query Hive tables.
  • MapR does not support HDFS encryption in Hive tables.
  • MapR does not support HBase with Hive-2.1.1 starting from mapr-core-6.0.0.
  • MapR does not support LLAP with Hive-2.1.1 as Apache Slider is not a MapR ecosystem component.
  • Starting from Hive 2.1, Hive needs to run the schematool command as an initialization step.

New Features

  • Added PAM authentication support for HiveServer2 Web UI.
  • Added REST API WebHCat SSL encryption support.
  • Added HiveMetastore password encryption.
  • Added separate files for HiveServer2 and HiveMetastore logs.


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.

Known Issues and Limitations

  • The hive-site.xml file permissions is 640.
  • For accessing and using Hive, administrators have the ability to manage permissions for "Other" users. There are at least two available options on how to enable the using of hive-site.xml:
    1. Add users who want to work with Hive to a mapr group.
    2. Set permission to 644 to make it world-readable.
