> Key: FLINK-17726
> URL: https://issues.apache.org/jira/browse/FLINK-17726
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination, Runtime / Task
> Affects Versions: 1.11.0, 1.12.0
> Reporter: Zhu Zhu
> Priority: Minor
> Labels: auto-deprioritized-critical, auto-deprioritized-major

> JobManager will not trigger failure handling when receiving CANCELED task
> update.
> This is because CANCELED tasks are usually caused by another FAILED task.
> These CANCELED tasks will be restarted by the failover process triggered
> FAILED task.
> However, if a task is directly CANCELED by TaskManager due to its own runtime
> issue, the task will not be recovered by JM and thus the job would hang.
> This is a potential issue and we should avoid it.
> A possible solution is to let JobManager treat tasks transitioning to
> CANCELED from all states except from CANCELING as failed tasks.
