> A common source of user difficulty on a secure cluster is understanding which paths should
be owned by which users. The task log directory in particular is often missed, since it has
to be owned by mapred but may be inside a logs dir which has different ownership. Right now
the user has to spelunk in the code to understand the exception they get if this dir has bad
ownership.
