>
> The delicate interplay of the {{CheckpointCoordinator}} and the 
> {{SavepointCoordinator}} requires that unknown checkpoint messages are not 
> discarded but given to the other coordinator. If both coordinator don't 
> accept the checkpoint message, then the associated state will be discarded by 
> the {{JobManager}}.
