> Once an operator is fully finished (e.g., all its subtasks are finished) in
> one checkpoint, the state need to be recorded to skip the execution of this
> operator after recovery. Thus we should allow operators to report finished
> state so that CheckpointCoordinator could identify fully finished operators
> for each checkpoint.
