Apache flink 用于运行flink应用程序的纱线web ui可以'；不能打开

我使用的是flink 1.3，我已经提交了一份flink申请，工作模式如下：

flink run -m yarn-cluster  ....

从控制台上，我看到应用程序已经启动，我可以看到mysql的接收器

但是，当我在Thread web ui上导航到这个正在运行的应用程序并单击它打开flink web ui时

flink ui未打开，出现如下错误，我想问一下这里出了什么问题，谢谢

你运行的flink 1.3.0的确切版本是什么？这看起来像是一个类路径问题。由于您在Thread上运行集群，您的类路径上可能会有另一个netty版本。也许您可以检查并发布用于启动纱线应用程序的类路径。
