我的代码是这样的：

String zkAddress = "...";  // example
ExponentialBackoffRetry retryPolicy = new ExponentialBackoffRetry(1000, 3);
CuratorFramework client = CuratorFrameworkFactory.builder()
                    .connectString(zkAddress)
                    .retryPolicy(retryPolicy)
                    .build();
client.start();

策展人框架版本是 3.1.0。我收到下面列出的错误。

该错误是由于该机器无权访问zookeeper服务器造成的。我换了另一台机器，它工作正常。
