com.baidu.disconf.core.common.utils.ZooUtils - cannot get host info

InetAddress.getLocalHost返回了一个错误的IP地址。为什么这个函数会返回一个错误的地址，因为这个函数的原理是通过获取本机的hostname，然后对此hostname做解析，从而获取IP地址的。那么问题来了，如果在本机的/etc/hosts文件里对这个主机名指向了一个错误的IP地址，那么InetAddress.getLocalHost就会返回这个错误的IP地址。当然如果你的hostname是到DNS去解析的，碰巧DNS上的信息也是错的，也同样是悲惨结局。
解决办法：
通过hostname查看主机名
修改/etc/hosts:添加一行：【本机IP地址】 【主机名】
