weixiuli updated SPARK-26288:
-----------------------------
Component/s: Spark Core
> add initRegisteredExecutorsDB in ExternalShuffleService
> -------------------------------------------------------
>
> Key: SPARK-26288
> URL: https://issues.apache.org/jira/browse/SPARK-26288
> Project: Spark
> Issue Type: New Feature
> Components: Kubernetes, Shuffle, Spark Core
> Affects Versions: 2.4.0
> Reporter: weixiuli
> Priority: Major
>
> As we all know that spark on Yarn uses DB to record RegisteredExecutors
> information which can be reloaded and used again when the
> ExternalShuffleService is restarted .
> The RegisteredExecutors information can't be recorded both in the mode of
> spark's standalone and spark on k8s , which will cause the
> RegisteredExecutors information to be lost ,when the ExternalShuffleService
> is restarted.
> To solve the problem above, a method is proposed and is committed .
