KeeperErrorCode = Unimplemented for /service 错误

使用Curator时报错，原因是因为版本问题

zookeeper版本：zookeeper-3.4.8

cuartor版本：3.2.0

看Curator官网的声明：

地址：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。
