Amar Kamat updated MAPREDUCE-807:
---------------------------------
Release Note: The JobTracker tries to delete the mapred.system.dir when it
is starting up (with the job recovery disabled). The fix provided by this jira
is that JobTracker will fail (bail out) with AccessControlException if it fails
to delete files/directories in mapred.system.dir due to access control issues.
> Stray user files in mapred.system.dir with permissions other than 777 can
> prevent the jobtracker from starting up.

> With restart disabled, the jobtracker does a _rm -rf_ of the
> mapred.system.dir. If the mapred.system.dir contains user files with
> permissions other than 777 then the jobtracker gets stuck in a loop trying to
> delete the mapred.system.dir (and each time failing with
> AccessControlException).
