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

             Summary: All task state changes should be notified to SchedulingStrategy (SchedulerNG)
                 Key: FLINK-14233
                 URL: https://issues.apache.org/jira/browse/FLINK-14233
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.10.0
            Reporter: Zhu Zhu
             Fix For: 1.10.0


{{SchedulingStrategy}} requires task states to make scheduling decisions.
According to {{SchedulingStrategy#onExecutionStateChange}} definition, all task state changes should be notified to {{SchedulingStrategy}}, including those from TMs and from within JM.
This can be helpful for a more flexible scheduling.

In the worst case, if some states are not supposed to be notified for some concerns, we should document it for that interface.
