Ambari version is 2.5

This issue is appearing on master node. All the services on master node is down.

Initially one of the data node was not able to make connection with master node. It seems that firewalld was not disable. we install the service and disabled it. and restarted ambari. After restarting ambari all the services on master node went down with above error. As this is master node so we wouldn't able to re-set ambari or reinstall it.

Is that ambari-agent service still running? Or try to restart it.

[root@hdptest ~]# /etc/init.d/ambari-agent status
Found ambari-agent PID: 63290
ambari-agent running.
Agent PID at: /run/ambari-agent/ambari-agent.pid

Thanks Mark. Stopping and Starting agent (on masternode) resolved the problem
