-------------------------------------

             Summary: OutputCommitCoordinator should not allow commits for 
already failed tasks
                 Key: SPARK-19631
                 URL: https://issues.apache.org/jira/browse/SPARK-19631
             Project: Spark
          Issue Type: Bug
          Components: Scheduler
    Affects Versions: 2.1.0
            Reporter: Patrick Woody


This is similar to SPARK-6614, but there a race condition where a task may fail 
(e.g. Executor heartbeat timeout) and still manage to go through the commit 
protocol successfully. After this any retries of the task will fail 
indefinitely because of TaskCommitDenied.
