> The state of the parentQueue and its childQeues need to be synchronized. 
> * If the state of the parentQueue becomes STOPPED, the state of its childQueue need to
become STOPPED as well. 
> * If we change the state of the queue to RUNNING, we should make sure the state of all
its ancestor must be RUNNING. Otherwise, we need to fail this operation.
