Review Comment:
@saihemanth-cloudera as per HIVE-16997 bit vector is set to true for tpcds
tests even if default value is false making it go back to `aggrStatsUseJava`
and even if i set it to false to fall back to `aggrStatsUseDB` the results are
different for .out files of tpcds queries.
So my concern is do I need to first obtain those different results generated
via `aggrStatsUseDB` and then run performance testing while validating with
those results.
