Subject [jira] [Commented] (HIVE-3891) physical optimizer changes for auto sort-merge join
Date Wed, 27 Feb 2013 03:25:11 GMT


Vikram Dixit K commented on HIVE-3891:

Hi Namit,

In case of the test auto_sortmerge_join_1.q, I see the output does not seem to be an SMB join
on the partitioned table. I am seeing similar behavior when I run on a partitioned table as
well. Is there any reason why we are not converting the join to an SMB map-join in the case
of partitioned table?
