Apache Spark reassigned SPARK-30191:
------------------------------------
Assignee: Apache Spark
> AM should update pending resource request faster when driver lost executor
> --------------------------------------------------------------------------
>
> Key: SPARK-30191
> URL: https://issues.apache.org/jira/browse/SPARK-30191
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 3.1.0
> Reporter: Max Xie
> Assignee: Apache Spark
> Priority: Minor
>
> I run spark on yarn. I found that when driver lost its executors because of
> machine hardware problem and all of service includes nodemanager, executor on
> the node has been killed, it means that Resourcemanager can't update the
> containers info on the node until Resourcemanager try to remove the node,
> but it always takes 10 mins or longger, and in the meantime, AM don't add the
> new resource request and driver missing the executors.
> So maybe AM should add the factor `numExecutorsExiting` in YarnAllocator's
> method `
> updateResourceRequests` to optimize it.
