Todd Lipcon commented on MAPREDUCE-2332:
----------------------------------------
This should probably be re-targeted at MR2 in trunk, and the original patch
used on branch-0.20 security. I probably won't get to it for a little while,
but if someone else has some spare time, happy to review.
> Improve error messages when MR dirs on local FS have bad ownership

> 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.
