Kafka Consumer Error-提供的xxxx节点名或servname或未知

问题描述

使用以下命令运行控制台使用者时

When running the console consumer using the following command

我遇到以下错误

Exception in thread "main" java.net.UnknownHostException: HQSML-142453: HQSML-142453: nodename nor servname provided, or not known
    at java.net.InetAddress.getLocalHost(InetAddress.java:1473)

现在，此命令在连接到工作网络时可以正常工作，但在从我的家庭网络运行时则不能正常工作.

Now this command worked fine when connected to the work network but not when running from my home network.

检查系统的主机名，我确实得到了正确的响应

Checking the hostname of the system I do get the correct response

看了一点之后，我注意到Kafka服务器的配置如下

After reading a bit, I noticed that the Kafka server configuration has the following

我更新了主机名，但似乎没有帮助.关于可能出现问题的任何想法.

which i updated to include my hostname but that didn't seem to help. Any ideas on what could be the problem here.

我知道这是与某些网络接口相关的，但是不能缩小到它的范围.

I know this is some networking interface related but cannot narrow it down to what it is.

config:优胜美地，osx jdk 7，kafka v0.8.1.1

config: Yosemite, osx jdk 7, kafka v0.8.1.1

推荐答案

尝试以下操作；

运行

ping HQSML-142453

如果ping不起作用，则意味着您没有在/etc/hosts或路由器DNS中配置的主机名.因此，您必须编辑/etc/hosts并将HQSML-142453名称映射到kafka运行所在的IP地址，或者将其映射到路由器DNS中.

If the ping is not working that means you don't have have the hostname configured in /etc/hosts or in your router DNS. So you must either edit the /etc/hosts and map your HQSML-142453 name to the IP address where your kafka is running or map it in your router DNS.

映射必须类似于/etc/hosts中的以下内容；

Mapping must look like the following in /etc/hosts;

127.0.0.1  HQSML-142453
