我在尝试从hortonworks hdp沙盒外部向apachekafka主题生成消息时遇到问题。现在我正在使用部署到azure的2.5版本，但是我在本地virtualbox上使用hdp2.6时遇到了类似的行为。我能够打开端口6667并确认tcp连接正在通过vm。我还可以访问主题列表。
使用侦听器=plaintext://0.0.0.0:6667

添加了以下配置条目：
播发端口=6667
播发的.listeners=plaintext://my_public_ip:6667
advised.host.name=我的\u公共\u ip
结果：

你能给我出什么问题的建议吗？我现在想继续用沙箱。
我终于成功了。这就是解决方案：

advertised.listeners=PLAINTEXT://sandbox.hortonworks.com:6667

似乎我的Kafka只能在主机名给定的情况下与代理对话，而不是ip。。。
