> Today the JobTracker, upon a heartbeat request, calls JobInProgress which
> calls TaskInProgress which internally calls JobTracker. It will be nice if we
> can get rid of these cyclic calls. Ideally JobInProgress should not know
> about JobTracker and TaskInProgress should not know about JobInProgress and
> JobTracker.
