Review Comment:
@okumin the reduction in size here is due to the map side aggregation (which
is set to true as part of this qtest) which happens when tez container size was
increased to 256. This aggregation did not run due to insufficient memory
earlier. I have added the detailed description related to this change in the
JIRA association with the commit here:
[HIVE-28396](https://issues.apache.org/jira/browse/HIVE-28396) . Please take a
look.
