A JobInProgressLIstener can change a job without informing other listeners
--------------------------------------------------------------------------

                 Key: HADOOP-4521
                 URL: https://issues.apache.org/jira/browse/HADOOP-4521
             Project: Hadoop Core
          Issue Type: Improvement
          Components: mapred
            Reporter: Amar Kamat


As of now the {{JobInProgressListener}} adds itself to the {{JobTracker}} and gets updated/informed.
Some of there {{JobInProgressListener}}'s control these changes/events (e.g.  {{EagerTaskInitializer}}).
The issue with this model is that a listener can change the job without informing other listeners.
