Devaraj Das updated MAPREDUCE-915:
----------------------------------
Attachment: 915-4.patch
Thanks for the review, Vinod! Attached is the patch with the suggested changes.
The one thing which I and Owen felt should be left as is is to have the same
file for writing the commands for launching tasks and debug scripts.
> For secure environments, the Map/Reduce debug script must be run as the user.

> 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.
