使用curator连接zookeeper后，创建节点时，报如下错误：

org.apache.zookeeper.KeeperException$UnimplementedException: KeeperErrorCode = Unimplemented for /com.xuan.rpc.service.UserService/provider/127.0.0.1:8990

原因：

是版本的问题

zookeeper版本：zookeeper-3.4.6  
cuartor版本：4.3.0

看Curator官网的声明：  
地址：[http://curator.apache.org/][http_curator.apache.org]  
The are currently two released versions of Curator, 2.x.x and 3.x.x:

Curator 2.x.x - compatible with both ZooKeeper 3.4.x and ZooKeeper 3.5.x  
Curator 3.x.x - compatible only with ZooKeeper 3.5.x and includes support for new features such as dynamic reconfiguration, etc.  
版本不匹配的问题，我这里是使用的curator版本过高，使用2.xx就没有问题了。我自己使用的是：2.13.0
