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.
