Devaraj Das updated MAPREDUCE-915:
----------------------------------

    Attachment: 915.2.patch

Ok this patch adds the permission/ownership checks of the debugout file. I also removed TestMiniMRMapRedDebugScript.java
since the new tests cover the test there and more..

> The Taskcontroller model allows admins to set up a cluster configuration that runs tasks
as users. The debug script feature of Map/Reduce provided by the configuration options: mapred.map.task.debug.script
and mapred.reduce.task.debug.script need to be run as the user as well in such environments,
rather than as the tasktracker user.
