java.net.UnknownHostException: master

1：如果你报这个错误，第一反应应该是本地的host文件没有配置服务器名称和对应的ip地址，这个反应就对了。贴一下错误和解决方法：

windows下开发大数据相关的应用程序，HBase部署在linux环境中，在运行调试时可能会出现无法找到主机，类似异常信息如上所贴：
解决办法如下：
在C:\WINDOWS\system32\drivers\etc\hosts文件末尾添加如下信息：

192.168.199.130 master
192.168.199.131 slaver1
192.168.199.132 slaver2
192.168.199.133 slaver3
192.168.199.134 slaver4
192.168.199.135 slaver5
192.168.199.136 slaver6

停更......
