Suman Sehgal commented on HADOOP-3913:
--------------------------------------
User mentioned here is not a superuser but group is "supergroup". Tried above
mentioned scenario after changing the group of the user but copying is still
possible.
> Distcp allows copy even if directory permissions are 000.
