> Using the rename functionality in Ambari YARN Queue Manager, it is possible to set multiple queues of the same name.
>  # On a new, empty cluster, create an "example" parent queue, and refresh YARN config
>  # Create another new parent queue named "MainExample"
>  # Add two leaf queues into "MainExample", but note that Ambari will indicate that a leaf queue named "example" cannot be created as a queue with that name already exists. Therefore we now call the new leaf queues "leaf1" and "leaf2" instead.
>  # The rename option will allow to rename the queue "leaf1" into "example" without any error (this is the bug, as it should give the same error as in step 3).
>  # Saving and attempting to use the configuration after these steps will result in RM failing with a variety of errors.
> We need logic in the Ambari YARN Queue Manager to verify new queues for duplicate queue names when using the rename function.
