>
> 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.
