Remove cyclic calls between JobTracker, JobInProgress and TaskInProgress
------------------------------------------------------------------------
Key: HADOOP-5639
URL: https://issues.apache.org/jira/browse/HADOOP-5639
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Reporter: Amar Kamat
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.
