[jira] [Created] (SPARK-21821) Force kill the
CoarseGrainedExecutorBackend process which is likely be orphaned
zuotingbing created SPARK-21821:
-----------------------------------
Summary: Force kill the CoarseGrainedExecutorBackend process which is likely be orphaned
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
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.
