      Description

      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

             // Sanity check
            if (!(newlyParsedQueue instanceof ParentQueue) || !newlyParsedQueue
                .getQueuePath().equals(getQueuePath())) {
              throw new IOException(
                  "Trying to reinitialize " + getQueuePath() + " from "
                      + newlyParsedQueue.getQueuePath());
            }
      

      Expected Behavior:
      Converting a Parent Queue to leafQueue on refreshQueue needs to be supported.
