Tongjie Chen commented on HIVE-6785:
------------------------------------

This patch involves deleting file and adding new files (mv),  and there is no instruction to delete/add if using git in https://cwiki.apache.org/confluence/display/Hive/HowToContribute; however my patch is using git diff, if that does not work, I will resubmit a patch using svn.
