Zhenxiao Luo commented on HIVE-2874:
------------------------------------
@Namit: My understanding in the old patch is incorrect. So, if an external
table's partition is renamed, its location should not change, but I could do
select/where using the new partition name. Correct me if my understanding is
still wrong.
I also updated my patch at:

> Renaming an external partition will change the location of that partition to
> the default location of a managed partition with the same name.
> E.g. If ex_table is external and has partition part=1 with location
> /.../managed_table/part=1
> Calling ALTER TABLE ex_table PARTITION (part = '1') RENAME TO PARTITION (part
> = '2');
> Will change the location of the partition to /.../ex_table/part=2
