> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3167
> Project: ZooKeeper
> Issue Type: New Feature
> Affects Versions: 3.4.5, 3.5.0
> Reporter: 田毅群
> Assignee: maoling
> Priority: Minor
> Labels: patch, pull-request-available
> Fix For: 3.6.0

> Time Spent: 2h 40m
> Remaining Estimate: 0h

> 1. In production environment, there will be always a situation that there are
> a lot of recursive sub nodes of one node. We need to count total number of it.
> 2. Now, we can only use API getChildren which returns the List<String> of
> first level of sub nodes. We need to iterate every sub node to get recursive
> sub nodes. It will cost a lot of time.
> 3. In zookeeper server side, it uses Hasp<String, DataNode> to store node.
> The key of the map represents the path of the node. We can iterate the map
> get total number of all levels of sub nodes of one node.
