Cao Manh Dat commented on SOLR-10619:
-------------------------------------

But instead of refetch the child list from ZK when there's no node. I think we 
should try to go to next node name we have in memory.

> When DQ.knowChildren is not empty, DQ should not refetch node children in 
> case of single consumer

> Right now, for every time childWatcher is kicked off. We refetch all children 
> of DQ's node. It is a wasted in case of single consumer.
