1.配置mapred-site.xml（默认没有mapred-site.xml文件，从mapred-site.xml.template文件复制一份，改名为mapred-site.xml就可以）
2.配置yarn-site.xml

3.向其他节点同步yarn配置（deploy.sh etc/ /usr/hadoop/app/hadoop/ all）
在hadoop001节点上执行（sbin/start-yarn.sh）
在hadoop002节点上面执行（sbin/yarn-daemon.sh start resourcemanager）
访问hadoop001的web页面，如下
访问hadoop002的web页面，如下
6.查看ResourceManager状态
如果上面执行没有异常，说明YARN安装成功
