> Key: FLINK-20222
> URL: https://issues.apache.org/jira/browse/FLINK-20222
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Reporter: Jiangjie Qin
> Assignee: Stephan Ewen
> Priority: Critical
> Fix For: 1.12.0
>
>
> Right now, if a job failed before the first successful checkpoint, the
> CheckpointCoordinator will not reset the OperatorCoordinator state. This may
> leave the OperatorCoordinators in inconsistent state.
> The CheckpointCoordinator should also reset the OperatorCoordinator state in
> this case, just like it does for the master hooks. It essentially means
> "reset to no checkpoint". There are two options for the fix:
> # Add a reset() method to the OperatorCoordinator.
> # Call resetToCheckpoint(null) on the OperatorCoordinator.
