Class hook for Tasktracker JVM start/stopSaptarshi Guha 2010-03-14, 07:50
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 |
