> Currently redundant task manager check in DeclarativeSlotManager only compare
> free slots with required redundant slots.
> when there are no enough resources in YARN/Kubernetes, this mechanism will
> always try to request new task manager.
> there are two way to address this.
> 1. maintain the state of redundant workers to avoid request twice
> 2. only try to request redundant workers when there is no pending worker
> The first way will make the logic of redundant worker too complicated, I
> would like to choose the second way
> Looking forward to any suggestion.
