Namit Jain commented on HIVE-2874:
----------------------------------

You are right. The location should not change by a rename in external's table 
partition.
                
> Renaming external partition changes location

> 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
