Review request for Ambari and Srimanth Gunturi.


Bugs: AMBARI-15879
    https://issues.apache.org/jira/browse/AMBARI-15879


Repository: ambari


Description
-------

Observed this in HDP 2.3.2

Original hive tez container size: 24576  
Original tez.runtime.io.sort.mb: 14950 or around this value

Changed hive tez container size to 16384. But tez.runtime.io.sort.mb remained
at 14 GB. Hive queries starts failing due to mem issue.

Ideally, when hive tez container size is adjusted, tez.runtime.io.sort.mb
should also be auto-adjusted in ambari (or a warning would be useful).
