> Key: FLINK-21821
> URL: https://issues.apache.org/jira/browse/FLINK-21821
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Network, Runtime / Task
> Affects Versions: 1.13.0
> Reporter: Kezhu Wang
> Priority: Minor
> Labels: auto-deprioritized-major
>
> I think {{AbstractInvokable.cancel}} should only do flag things but not
> closing staff. Otherwise task canceler and task thread will contend on these
> closing tasks.
> It is same for {{BatchTask.cancel}} which might be confirmed as one potential
> cause for FLINK-21728.
