Zhenxiao Luo commented on HIVE-2874:
------------------------------------
if it is an EXTERNAL_TABLE, the table's location is in StorageDescriptor, the
new patch shares the same parent path as the old path.
If it is a MANAGED_TABLE, the table's location could be get from Warehouse.

> 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
