> Work directory is not deleted in DistCache if Exception happen in
> downloadCacheObject. In downloadCacheObject, the cache file will be copied to
> temporarily work directory first, then the work directory will be renamed to
> the final directory. If IOException happens during the copy, the work
> directory will not be deleted. This will cause garbage data left in local
> disk cache. For example If the MR application use Distributed Cache to send a
> very large Archive/file(50G), if the disk is full during the copy, then the
> IOException will be triggered, the work directory will be not deleted or
> renamed and the work directory will occupy a big chunk of disk space.
