-Class hook for Tasktracker JVM start/stop
Saptarshi Guha 2010-03-14, 07:50
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?
