[jira] [Created] (FLINK-14363) No need to cancel vertex when its version is outdated in scheduling (SchedulerNG)

Zhu Zhu created FLINK-14363:
-------------------------------

             Summary: No need to cancel vertex when its version is outdated in scheduling (SchedulerNG)
                 Key: FLINK-14363
                 URL: https://issues.apache.org/jira/browse/FLINK-14363
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.10.0
            Reporter: Zhu Zhu
             Fix For: 1.10.0


DefaultScheduler currently will cancel latest execution of a vertex when the vertex version is outdated. This is undesirable.
I'd propose to remove the vertex cancel process in {{DefaultScheduler#stopDeployment}}. This is because the version of a scheduled vertex is only outdated after the vertex is canceled by others.
