Thomas Graves commented on MAPREDUCE-3824:
------------------------------------------
After some debugging, it appears that the size isn't being calculated properly
(set to 0) if the user specifies a directory to go into the distributed cache.
It only appears to happen if its a private cached directory. I'm working on a
patch.
Allen, can you confirm that your users were specifying a directory to be cached
and not a file?
