> Cancel zombie tasks in a result stage when the job finishes
> -----------------------------------------------------------
>
> Key: SPARK-25773
> URL: https://issues.apache.org/jira/browse/SPARK-25773
> Project: Spark
> Issue Type: Improvement
> Components: Scheduler
> Affects Versions: 2.4.0
> Reporter: Shixiong Zhu
> Assignee: Shixiong Zhu
> Priority: Major
>
> When a job finishes, there may be some zombie tasks still running due to
> stage retry. Since a result stage will never be used by other jobs, running
> these tasks are just wasting the cluster resource. This PR just asks
> TaskScheduler to cancel the running tasks of a result stage when it's already
> finished. Credits go to @srinathshankar who suggested this idea to me.
