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

Sreekanth Ramakrishnan commented on MAPREDUCE-915:
--------------------------------------------------

Sorry raising the fuss, talked with Devaraj and Hemanth offline, we can merge MAPREDUCE-913
after MAPREDUCE-915 is commited and merge effort would be lesser. Changing the issue link.

> 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.
