[jira] [Created] (SPARK-8297) Scheduler backend is not notified in case node fails in YARN

Mridul Muralidharan created SPARK-8297:
------------------------------------------

             Summary: Scheduler backend is not notified in case node fails in YARN
                 Key: SPARK-8297
                 URL: https://issues.apache.org/jira/browse/SPARK-8297
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.3.1, 1.2.2, 1.4.1
         Environment: Spark on yarn - both client and cluster mode.
            Reporter: Mridul Muralidharan
            Assignee: Mridul Muralidharan
            Priority: Critical


When a node crashes, yarn detects the failure and notifies spark - but this information is not propagated to scheduler backend (unlike in mesos mode, for example).

It results in repeated re-execution of stages (due to FetchFailedException on shuffle side), resulting finally in application failure.
