-------------------------------

             Summary: LazyFromSourcesSchedulingStrategy is possible to schedule non-CREATED vertices
                 Key: FLINK-20285
                 URL: https://issues.apache.org/jira/browse/FLINK-20285
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.11.0
            Reporter: Zhu Zhu
             Fix For: 1.12.0, 1.11.3


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[1].

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.
