> I encountered a reducer's OOM because of java.io.DeleteOnExitHook. And I 
> found out that the InternalCachedBag creates a seperate tmp file, and the tmp 
> files is deleted on exit. So the file delete hook caused the OOM. 
> Why not just hold the tmp file handle and spill only one tmp file?
> Too many tmp files may block the tasktracker start process, if the tmp files 
> are not cleaned on time and the tasktracker restarts at this specific time.
