Maven Apache管理员ZooKeeper-keeperrorCode=未实现，错误

我使用以下Apache Curator Maven依赖项：

    <dependency>
        <groupId>org.apache.curator</groupId>
        <artifactId>curator-x-async</artifactId>
        <version>4.0.1</version>
        <exclusions>
            <exclusion>
                <groupId>org.apache.zookeeper</groupId>
                <artifactId>zookeeper</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

但它失败了，但有以下例外：

我做错了什么以及如何修复它？

我使用的Apache Curator和ZooKeeper的组合不正确。目前，Apache Curator 4.0.1和ZooKeeper 3.5.4-beta的组合运行良好Apache Curator和ZooKeeper的组合不正确。现在，ApacheCurator 4.0.1和ZooKeeper 3.5.4-beta的组合运行良好，如果ZooKeeper服务器版本是3.4.x，那么下面的组合运行良好

<dependencies>
    <dependency>
        <groupId>org.apache.zookeeper</groupId>
        <artifactId>zookeeper</artifactId>
        <version>3.4.14</version>
    </dependency>
    <dependency>
        <groupId>org.apache.curator</groupId>
        <artifactId>curator-recipes</artifactId>

                <groupId>org.apache.zookeeper</groupId>

但是，要将Zookeeper 3.5.x与Curator 4.x一起用作客户端（用于节点容器等较新功能），请运行server 3.5.x版本，否则客户端将抛出未实现异常

如果Zookeeper服务器版本为3.4.x，则以下操作正常

<dependencies>
    <dependency>
        <groupId>org.apache.zookeeper</groupId>
        <artifactId>zookeeper</artifactId>
        <version>3.4.14</version>
    </dependency>
    <dependency>
        <groupId>org.apache.curator</groupId>

        <exclusions>
            <exclusion>
                <groupId>org.apache.zookeeper</groupId>
