Description

Currently, NodeChildrenChanged events are sent to all persistent watchers unconditionally in client. This requires server to never deliver NodeChildrenChanged for node's descendants. It can not be true. So we need to filter NodeChildrenChanged for persistent recursive watchers.

Splits from ZOOKEEPER-4466.
