[jira] [Resolved] (MAPREDUCE-156) ProcessTree.destroy() is sleeping for 5 seconds holding the task slot

Allen Wittenauer resolved MAPREDUCE-156.
----------------------------------------

    Resolution: Won't Fix

This is intentional to potentially give time for the process to clean up. Closing as won't fix.

> Currently, in ProcessTree.destroy(), after sending SIGTERM to the task JVM, TT sleeps for 5 seconds(default value of mapred.tasktracker.tasks.sleeptime-before-sigkill) before sending SIGKILL. This seems to be blocking the task slot(not getting released) for 5 seconds. We should avoid this so that another task could be launched in that slot immediately.
