    Description

      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.
