MIS commented on ZOOKEEPER-1022:
--------------------------------
It is not the functionality of the ZooKeeper to order the children as per the business logic of the application using it.
Further, I think we should not burden the Zookeeper to do things which hold little relevance to the core functionality of the ZooKeeper.
The use-case for which this issue has been raised can be achieved by having the required logic at the application side and not at the zookeeper side.
-1 from my side for this issue.
