[jira] [Commented] (SPARK-8297) 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.
