[jira] [Created] (SPARK-8167) Tasks that fail due to YARN preemption can cause job failure

Patrick Woody created SPARK-8167:
------------------------------------

             Summary: Tasks that fail due to YARN preemption can cause job failure
                 Key: SPARK-8167
                 URL: https://issues.apache.org/jira/browse/SPARK-8167
             Project: Spark
          Issue Type: Bug
          Components: Scheduler, YARN
    Affects Versions: 1.3.1
            Reporter: Patrick Woody


Tasks that are running on preempted executors will count as FAILED with an ExecutorLostFailure. Unfortunately, this can quickly spiral out of control if a large resource shift is occurring, and the tasks get scheduled to executors that immediately get preempted as well.

The current workaround is to increase spark.task.maxFailures very high, but that can cause delays in true failures. We should ideally differentiate these task statuses so that they don't count towards the failure limit.
