[jira] [Created] (FLINK-14232) Support full restarts for DefaultScheduler (SchedulerNG)

Zhu Zhu created FLINK-14232:
-------------------------------

             Summary: Support full restarts for DefaultScheduler (SchedulerNG)
                 Key: FLINK-14232
                 URL: https://issues.apache.org/jira/browse/FLINK-14232
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.10.0
            Reporter: Zhu Zhu
             Fix For: 1.10.0


Full restarts(failGlobal) is widely used in ExecutionGraph components and even other components to recover from an inconsistent state. 

We need to support it for DefaultScheduler to not break the safety net. More details see [here|https://github.com/apache/flink/pull/9663/files#r326892524].

There can be follow ups of this task to replace usages of full restarts with JVM termination, in cases that are considered as bugs/unexpected to happen.
