> At the moment we use consumer running check in RemoteChannelStateChecker as a
> shortcut if consumer is done before the check has been accomplished then we
> skip the check.
> Ideally we should use closeFuture in SingleInputGate instead of consumer
> state for this. Although this shortcut is the best effort because the state
> change or gate close can happen concurrently right after this check,
> exposing consumer state to shuffle implementation looks unnecessary.
