Description

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.
