1.查找cm的guid存放目录发现在这个位置 /var/lib/cloudera-scm-agent/cm_guid
[rootxxx cloudera-scm-server]# find / -name *cm_guid*
/var/lib/cloudera-scm-agent/cm_guid 2.查看内容发现就是上面提示的811xxx查看文件时间是之前搭建的时间
cat /var/lib/cloudera-scm-agent/cm_guid
8115403a-7f9c-463f-b6d4-45fed899215b
3.停止agent节点后删除cm_guid并启动agent节点
systemctl stop cloudera-scm-agent
#这里等几秒服务停止后再删除
systemctl status cloudera-scm-agent
rm -f /var/lib/cloudera-scm-agent/cm_guid
systemctl start cloudera-scm-agent
4.查看agent日志一切正常
5.登录CM分配CDH一切正常。
