How to close a queue?

[Alton Patrick]

Trying to delete a Queue with kubectl, I get this error:

$ kubectl delete queues.scheduling.volcano.sh foo

Error from server: admission webhook "validatequeue.volcano.sh" denied the request: only queue with state `Closed` can be deleted, queue `foo` state is `Open`

How do I set the Queue's state to "Closed"? Can it be done with kubectl? I have tried updating the the object's manifest with "kubectl apply", but it doesn't not seem to have an effect.

It's required to close queue firstly after all job completed, and then delete the queue :).

And here's more info about this question:
