Kevin Wilfong commented on HIVE-4042:
-------------------------------------
What if the table is not bucketed but the partitions are. Granted this is an
unusual case, but it's possible that this will prevent bucket map join or SMB
join from being used where it normally would be.
> ignore mapjoin hint
