Github user StephanEwen commented on the issue: https://github.com/apache/flink/pull/3113 Considering the possible state transitions: ## ExecutionState - `RECONCILING` can only be entered from `CREATED` Simple: - `RECONCILING` can go to `RUNNING` if the task was reconciled - `RECONCILING` can go to `FAILED` if the task was not reconciled Complex: - For `RECONCILING` to go to `FINISHED`, `CANCELED`, it would mean that the TaskManager that has the task would report (when registering at the JobManager) a task that is no longer executing. To do that, the TaskManager would need to "remember" tasks that completed and where it did not get an acknowledgement from the JobManager for the execution state update. Is that anticipated? ## JobStatus - `RECONCILING` can only be entered from `CREATED` Simple: - `RECONCILING` can go to `RUNNING` - if all TaskManagers report their status and tasks as running - `RECONCILING` can go to `FAILING` - if not all tasks were reported. Complex: - For reconciling to go to into `FINISHED`, we'd need that the `ExecutionState` can go to `FINISHED`. What do you think about only doing the "simple" option in the first version?
