> 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.
