Review request for Ambari, Alejandro Fernandez and Nate Cole.
Bugs: AMBARI-10160
https://issues.apache.org/jira/browse/AMBARI-10160
Repository: ambari
Description
-------
Hive requests using the hive client use Tez instead of MR for the engine. This
causes new Tez sessions every time `hive` is invoked. Alerts uses `hive` for
the metastore check, which overloads the RM with too many Tez sessions.
Switching to use `mr` as the engine.

Testing
-------
Deployed changes and verified hive metastore alert behaved correctly and that
no more Tez sessions were show in YARN.
Thanks,
Jonathan Hurley
