> 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.
