> Currently {{TaskTracker.TaskInProgress.taskFinished}} handles the responsibility of executing
the debug scripts for Map/Reduce tasks. Ideally we should keep this confined to TaskRunner
(which currently executes the actual tasks) or a separate pre/post processing classes.
> The current situation leads to bugs like HADOOP-3696.
