amazon ec2 4 node cluster shows lost heart beat for all services and not able to start any services
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
