Subject [jira] [Commented] (HIVE-11107) Support for Performance regression test suite with TPCDS
Date Fri, 04 Dec 2015 01:09:10 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15039525#comment-15039525

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}
