> Linux task controller is too strict now w.r.t the initial ownership of the files/dir
that it tries to make as secure as possible. Currently, it expects, for e.g, the mapred-local/tasktracker/user-dir
to be both user-owned and group-owned by TT. This leads to unrecoverable failures in some
corner cases.
> It can instead allow the files/dirs to be owned either by TT *or* by the jobOwner.
