这里的问题主要是服务端的zookeeper版本和客户端的zookeeper版本不同。
我这里的zookeeper的服务端版本是3.4，客户端版本是3.5，然后就会导致各种各样的问题。
这里我们只要降低一下curator-framework的版本就可以了，
<version.curator>2.12.0</version.curator>
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-framework</artifactId>
<version>${version.curator}</version>
</dependency>
最终启动成功！
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
