> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: wuyi

> Priority: Major
>
> Currently, we use cleanupBarrierStage when detecting different barrier sync
> types in a single sync. This cause a problem that a new `ContextBarrierState`
> can be created again if there's following requesters on the way. And those
> corresponding tasks will fail because of killing instead of different barrier
> sync types detected.
