-------------------------------------
Summary: Task can be stuck in deploying state forever when
canceling job/failover
Key: FLINK-37024
URL: https://issues.apache.org/jira/browse/FLINK-37024
Project: Flink
Issue Type: Bug
Components: Runtime / Task
Affects Versions: 1.20.0
Reporter: Zhanghao Chen
We observed that task can be stuck in deploying state forever when the task
initializing logic has some issues. Cancelling the job / failover caused by
failures of other tasks will also get stuck as the cancel watch dog won't work
for tasks in CREATED/DEPLOYING state at present. We should make cancel watch
dog cover tasks in DEPLOYING as well (no need for tasks in CREATED state has
there is no real logic between CREATED->DEPLOYING).
