标红的IP:172.16.145.114为成功启动的resourcemanager，上面的报错信息是启动失败的rm(172.16.145.115)报的错
错误显示114的8088端口已经在使用，跟我115有毛关系啊。
检查配置文件发现 两个rm中的yarn-site.xml中的 yarn.resourcemanager.ha.id设置成了同一个rm的主机名
解决办法：rm1的yarn-site的yarn.resourcemanager.ha.id设置成rm1
rm2的yarn-site的yarn.resourcemanager.ha.id设置成rm2
<!--在node04上配rm1，node05上配rm2,slave节点不用配这个属性--> <property> <name>yarn.resourcemanager.ha.id</name> <value>rm1</value> </property>
错误总结：一直以为两个resourcemanager配置文件是一样的，没有注意到这个属性。
对于这个属性两个rm的yarn-site设置不一样，而且slave中不需要配，其他属性暂时还发现，所有节点保持一致就行了
