> We observed that task can be stuck in deploying state forever when the task
> loading/instantiating 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).
