Review request for Ambari and Dmitro Lisnichenko.


Bugs: AMBARI-8190
    https://issues.apache.org/jira/browse/AMBARI-8190


Repository: ambari


Description
-------

We have seen issues with the default permgen space limit of hiveserve2.  
We have verified that 512MB is a good limit for HS2.

-XX:MaxPermSize=512m needs to be passed as java command argument of HS2.

In case of gsInstaller, this was done using HADOOP_CLIENT_OPTS environment
variable. See <https://github.com/hortonworks/gsInstaller/commit/fa29ae6e228b0
bd24876062bd0a0274e75610b7d>
