> Issue Type: Bug
> Components: Runtime / Coordination

>
> LazyFromSourcesSchedulingStrategy is possible to schedule vertices which are
> not in CREATED state. This will lead result in unexpected check failure and
> result in fatal error (see attached error).
> The reason is that the status of a vertex to schedule was changed in
> LazyFromSourcesSchedulingStrategy#allocateSlotsAndDeployExecutionVertices()
> during the invocation of schedulerOperations.allocateSlotsAndDeploy(...) on
> other vertices.
> e.g. ev1 and ev2 are in the same pipelined region and are restarted one by
> one in the scheduling loop in
> LazyFromSourcesSchedulingStrategy#allocateSlotsAndDeployExecutionVertices().
> They are all CREATED at the moment. ev1 is scheduled first but it immediately
> fails due to some slot allocation error and ev2 will be canceled as a result.
> So when ev2 is scheduled, its state would be CANCELED and the state check
> failed.
> More details see FLINK-20220.
