Subject [jira] [Updated] (HIVE-4502) NPE - subquery smb joins fails
Date Mon, 13 May 2013 06:39:27 GMT


Vikram Dixit K updated HIVE-4502:

    Attachment: HIVE-4502-1.patch

Hi [~navis]

My attached patch actually retains the SMB join and I feel it is a better plan over-all than
converting all of the joins to reduce side joins. It would be great if you could take a look
and let me know your opinion. All existing unit tests pass with this patch.
