> 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.
