2 解决，删除cm_guid然后重启服务

产生的原因是服务器以前作为集群节点安装过agent服务，再次使用时没有卸载干净。

解决办法：

rm -rf /var/lib/cloudera-scm-agent/cm_guid

service cloudera-scm-agent restart

 

 

 

cd /opt/cloudera-manager/cm-5.16.1/lib/cloudera-scm-agent

sudo rm -rf cm_guid

 

sudo /opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-agent restart
