Review Comment:
@ayushtkn This reduction is due to map side aggregation (which is set to
true as part of this qtest) that happens due to increase in tez container size.
This aggregation was not happening earlier with lower tez container size. I
have added the complete details of this in JIRA:
[HIVE-28396](https://issues.apache.org/jira/browse/HIVE-28396).
