java.net.BindException: Problem binding to [hadoop103:8031] java.net.BindException

ResourceManger启动失败，Namenode启动成功，这个问题排查了好久

在hadoop-2.7.6/logs/yarn-root-resourcemanager-hadoop102.log下查看日志 
报错是java.net.BindException: 无法指定被请求的地址。　　

解决方式：

如果在完全分布式部署，Namenode和ResourceManger如果不是同一台机器，不能在NodeManager上启动 yarn，应该在ResouceManager所在的机器上启动yarn

报错信息：
