Date Wed, 16 Feb 2011 07:32:57 GMT
Improve error messages when MR dirs on local FS have bad ownership
------------------------------------------------------------------

                 Key: MAPREDUCE-2332
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2332
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
             Fix For: 0.23.0
         Attachments: mr-2332.txt

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.
