[jira] [Created] (SPARK-8323) Remove mapOutputTracker field in TaskSchedulerImpl

patrickliu created SPARK-8323:
---------------------------------

             Summary: Remove mapOutputTracker field in TaskSchedulerImpl
                 Key: SPARK-8323
                 URL: https://issues.apache.org/jira/browse/SPARK-8323
             Project: Spark
          Issue Type: Improvement
          Components: Scheduler, Spark Core
            Reporter: patrickliu


Because TaskSchedulerImpl's mapOutputTracker field is only referenced once in TaskSetManager.
I think we could remove the mapOutputTracker field in the TaskSchedulerImpl class.
Instead, we could reference the mapOutputTracker from SparkEnv directly in TaskSetManager.
