Subject [jira] Commented: (MAPREDUCE-915) For secure environments, the Map/Reduce debug script must be run as the user.

Vinod K V commented on MAPREDUCE-915:
-------------------------------------

We should have a test to verify the ownership of the debug output file as well as its file
permissions. That will kind of assert that the debug script is indeed run as the user and
not the TT. We can add/modify tests in TestTaskTrackerLocalization for this.

> 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.
