Not enough details provided like HDP version, Ambari version
ambari-agent restart in all the nodes and see if it helps.
node 1: ambari-server & ambari-agent
node 2: ambari-agent
node 3: ambari-agent
node 4: ambari-agent
restarted all agents, still in the ambari dashboard all hosts says heartbeat failure.
I'm using elastic ip with amazon ec2

Please see my host config screen.
also i updated the file /etc/ambari-agent/conf/ambari-agent.ini to point to ambari server

invalid /etc/hosts file entry caused this.
