Ashutosh Chauhan commented on HIVE-11107:
-----------------------------------------
1. Why do we have sql scripts for stats copied in? They should be sourced from
original location which is in metastore/scripts/derby/
2. Please add comments in TestPerfCliDriver.vm on how is it different from
TestCliDriver.vm
3. I also dont see any changes in ptest2/ How are we making sure QA will pick
this new Driver.

> Support to add TPCDS queries to the performance regression test suite with
> Hive CBO turned on.
> This benchmark is intended to make sure that subsequent changes to the
> optimizer or any hive code do not yield any unexpected plan changes. i.e.
> the intention is to not run the entire TPCDS query set, but just "explain
> plan" for the TPCDS queries.
> As part of this jira, we will manually verify that expected hive
> optimizations kick in for the queries (for given stats/dataset). If there is
> a difference in plan within this test suite due to a future commit, it needs
> to be analyzed and we need to make sure that it is not a regression.
> The test suite can be run in master branch from itests by
> {code}
> mvn test -Dtest=TestPerfCliDriver
> {code}
