[jira] [Created] (SPARK-20163) Kill all running tasks in a stage in case of fetch failure

Sital Kedia created SPARK-20163:
-----------------------------------

             Summary: Kill all running tasks in a stage in case of fetch failure
                 Key: SPARK-20163
                 URL: https://issues.apache.org/jira/browse/SPARK-20163
             Project: Spark
          Issue Type: Bug
          Components: Scheduler
    Affects Versions: 2.0.1
            Reporter: Sital Kedia


Currently, the scheduler does not kill the running tasks in a stage when it encounters fetch failure, as a result, we might end up running many duplicate tasks in the cluster. There is already a TODO in TaskSetManager to kill all running tasks which has not been implemented.
