Subject [jira] [Commented] (HIVE-8636) CBO: split cbo_correctness test
Date Thu, 06 Nov 2014 02:58:33 GMT


Sergey Shelukhin commented on HIVE-8636:

I cannot update the RB because the patch is too big. I did address the comment about stats
writer. There were no other significant changes... patches can be compared by applying to
a tree and doing "git difftool" with opendiff, diffmerge, meld or something (opendiff is available
by default on Mac)

> CBO correctness test is extremely annoying - it runs forever, if anything fails it's
hard to debug due to the volume of logs from all the stuff, also it doesn't run further so
if multiple things fail they can only be discovered one by one; also SORT_QUERY_RESULTS cannot
be used, because some queries presumably use sorting.
> It should be split into separate tests, the numbers in there now may be good as boundaries.
