Steve Loughran commented on HADOOP-13622:
-----------------------------------------

One challenge here is that we aren't going to easily tell if an FS is an object 
store, not unless HADOOP-9565 or equivalent gets in

> `-atomic` should not be supported while using `distcp` command in object file 
> system

> After discussing with [~ste...@apache.org] in HADOOP-13593, I get the point 
> that none of the object stores support atomic renames. So I file a new jira 
> and ready to provide a patch to disable `distcp -atomic`  in object file 
> system.
