Dubbo+Zookeeper报错KeeperException$UnimplementedException: KeeperErrorCode = Unimplemented

今天在运行spring-boot + dubbo的时候，zookeeper中注册的时候抛出一个异常，查看到我使用的curator-recipes版本是4.0+版本，依赖的zookeeper是3.5加版本，而我自己的zookeeper是3.4.x版本。
异常信息

说是由于Zookeeper版本问题，果然我的Zookeeper版本是3.4.x的
查看到我的pom依赖的zookeeper是3.5.x所以导致这个错误
在这里插入图片描述
更新版本

<dependency>
   <groupId>org.apache.curator</groupId>
   <artifactId>curator-recipes</artifactId>
   <version>4.0.1</version>
   先排除zookeeper
   <exclusions>
    	<exclusion>
    		<groupId>org.apache.zookeeper</groupId>
    		<artifactId>zookeeper</artifactId>
    	</exclusion>
    </exclusions>
</dependency>

添加zookeeper3.4.x版本
<dependency>
	<groupId>org.apache.zookeeper</groupId>
	<artifactId>zookeeper</artifactId>
	<version>3.4.7</version>
</dependency>

修改依赖之后重新运行成功。
