> Key: SPARK-21821
> URL: https://issues.apache.org/jira/browse/SPARK-21821
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 2.2.0
> Reporter: zuotingbing
> Assignee: Apache Spark
>
> In out production environments, it often happens that even the application
> has finished, but the CoarseGrainedExecutorBackend process still exists and
> take up the resource.
> Take a look at ExecutorRunner.scala, it maybe failed to terminate process in
> killProcess method for some reason. In this case, the process of
> CoarseGrainedExecutorBackend will likely be orphaned. It would be great to
> support a script to kill the CoarseGrainedExecutorBackend process forcibly.
