> If we configure CS such that all children of a parent queue are deleted and
> made as a leaf queue, then {{refreshQueue}} operation fails when
> re-initializing the parent Queue
> {code}
> // Sanity check
> if (!(newlyParsedQueue instanceof ParentQueue) || !newlyParsedQueue
> .getQueuePath().equals(getQueuePath())) {
> throw new IOException(
> "Trying to reinitialize " + getQueuePath() + " from "
> + newlyParsedQueue.getQueuePath());
> }
> {code}
> *Expected Behavior:*
> Converting a Parent Queue to leafQueue on refreshQueue needs to be supported.
