From your logs we see that agents are failing to communicate with ambari-server.

INFO 2017-05-05 14:05:11,156 NetUtil.py:67 - Connecting to https://centos7-node1:8440/ca

Please make sure that the agents are able to access the ambari-server hostname & port properly. There should be no iptables/firewall restriction.

Please check that you are able to do telnet from agent machine to connect to ambari server?

8440: Handshake Port for Ambari Agents to Ambari Server

8441: Registration and Heartbeat Port for Ambari Agents to Ambari Server

  # telnet centos7-node1 8440
  # telnet centos7-node1 8441
  # telnet centos7-node1 8080

Also on ambari server and agent hosts please make sure that the hostnames are resolvable throughout the cluster (means every host has the correct "/etc/hosts" entry to resolve other hosts.

The output of the following command shoudl be resolvable and consistent through out the cluster hosts.

# hostname -f
