Steve Loughran commented on HADOOP-16374:
-----------------------------------------
That early cleanup guarantees that even if the process is killed during the
wait, cleanup will happen
I'd prefer retaining the two calls, but having some state tracker which knows
not to do the second in shutdown (or just remove the hook)
> Fix DistCp#cleanup called twice unnecessarily
