Subject [jira] Created: (HADOOP-5639) Remove cyclic calls between JobTracker, JobInProgress and TaskInProgress
Date Wed, 08 Apr 2009 04:49:13 GMT
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.
