>             Project: Flink
>          Issue Type: Bug
>          Components: Runtime / Coordination, Runtime / Task
>    Affects Versions: 1.11.0, 1.12.0
>            Reporter: Zhu Zhu
>            Assignee: Nicholas Jiang
>            Priority: Critical
>             Fix For: 1.12.0, 1.11.1
> 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.
