Subject [jira] [Commented] (HIVE-4502) NPE - subquery smb joins fails
Date Tue, 04 Jun 2013 02:11:20 GMT


Vikram Dixit K commented on HIVE-4502:

[~navis] I misread the results of the test case from your patch. I was going through your
patch more meticulously and found that a few of the tests have different results. Particularly
those in auto_sortmerge_join_6.q. The count results seem to have changed.

HIVE-3891 converts SMB joins to map-joins when possible. Although that seems orthogonal to
this change, any idea as to why the join is still SMB?

Also attached a few more tests for this. The plans seem valid after applying your patch. I
will continue to review the patch.
