Apache Spark reassigned SPARK-38916:
------------------------------------
Assignee: Apache Spark
> Tasks not killed caused by race conditions between killTask() and launchTask()
> ------------------------------------------------------------------------------
>
> Key: SPARK-38916
> URL: https://issues.apache.org/jira/browse/SPARK-38916
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.2.1
> Reporter: Wei Xue
> Assignee: Apache Spark
> Priority: Minor
>
> Sometimes when the scheduler tries to cancel a task right after it launches
> that task on the executor, the KillTask and LaunchTask events can come in a
> reversed order, causing the task to escape the kill-task signal and finish
> "secretly". And those tasks even show as an un-launched task in Spark UI.
