Saisai Shao commented on SPARK-8297:
------------------------------------
OK, thanks [~mridulm80], I will take a try, from my understanding, akka will
also get notified if connection is abruptly lost, I didn't test it, will take a
try.
> 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: 1.2.2, 1.3.1, 1.4.1, 1.5.0
> Environment: Spark on yarn - both client and cluster mode.
> Reporter: 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.
