He Yongqiang commented on HIVE-2484:
------------------------------------
I haven't looked at partition's object to see if there is a method there. But
technically, the partition's columns are copied from tables right now. So after
a table's columns got changes, the old partitions can still have old ones,
though they are not used today.
> Enable ALTER TABLE SET SERDE to work on partition level
