Hyunsik Choi commented on TAJO-21:
----------------------------------
+1 for this patch. It works well. Due to the incompleteness of TajoClient
implementation, its unit tests require much out-of-scope work. So, this patch
without any unit test may be fine.
Besides, it would be better if the message is "ERROR: LOCATION must be a
directory."
Thanks!
