apache-kafka - 为什么服务器启动时会失败并显示 "java.net.SocketException: invalid argument"？

Question

卡夫卡0.8

我按照快速入门指南进行操作，当我进入第 2 步运行 bin/kafka-server-start.sh config/server.properties 时，我遇到了异常:

[2013-08-06 09:55:14,603] INFO 0 successfully elected as leader (kafka.server.ZookeeperLeaderElector)

我可能做错了什么？请指教。

这可能是名称解析问题，或者是 0.7 版本的剩余设置问题。

如果您要从 0.7 迁移，请参阅 migration guide .

如果您是新手，请确保/etc/hosts 中有一个准确的主机名条目。

例如给定一个 /etc/hostname 文件，其中包含

yourhostname

和一个接口(interface) (/sbin/ifconfig)，使用 10.181.11.14 示例 IP 进行监听

/etc/hosts 应正确将该名称映射到监听接口(interface):

10.181.11.14    yourhostname.yourdomain.com       yourhostname   someotheralias

您可以通过telnet到kafka端口并确保没有超时来测试它:

telnet yourhostname.yourdomain.com 9092
Trying 10.181.11.14...
Connected to yourhostname.yourdomain.com.
