Szehon Ho commented on HIVE-9975:
---------------------------------
Yea makes sense, although the message might make more sense as 'Rename
partition: source partition [part_name] does not exist', because 'renamed' make
it seem like its already renamed. Sorry to make you run the test again ,
wonder what you think.
> Renaming a nonexisting partition should not throw out NullPointerException
