> 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.
