 yarn-site.xml 配置

<property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
<property>
<name>yarn.resourcemanager.hostname</name>
<value>vm216</value>

</property>

解决方案  

由于hostname配置问题   阿里云 腾讯云 不能够配置公网ip

修改etc/hosts文件    

内网ip hostname

从新启动resourceManager    jps查看 启动成功
