Class hook for Tasktracker JVM start/stop
Hello,
The value mapred.job.reuse.jvm.num.tasks is the number of tasks a Tasktracker
will process before it shuts down and another Tasktracker starts, correct?

If so, is there a hook/class that can be called when the jvm(corresponding to
the TaskTracker) starts and one when it shuts down? Can this class be provided
with the Cofiguration/context object?

Much thanks
Saptarshi
