> 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.
