number of tasks on a node.

Hi.

 

How can node find out how many task are being run on it at a given time?

I want tasktracer nodes (which are assigned from amazon EC) to shutdown if
nothing is being run for some period of time, but don't yet see right way of
implementing this.

TaskTrackers are communicates with JobTracker so I guess you can
handle it via JobTracker.
