Paul Yang updated HIVE-1300:
----------------------------
Attachment: HIVE-1300.1.patch
Preliminary patch. Added an ALTER ... UPDATE for partitions to force firing of the hooks but I think it should be added for non-partitioned tables as well.

Namit Jain commented on HIVE-1300:
----------------------------------
Can you add a negative test also ? The partition does not exist.
Can you file a follow-up jira for the same functionality for a non-partitioned table ?
Also, can you confirm that no table internally is using 'UPDATE' as a column name.
