  • Installation failed. Failed to receive heartbeat from agent. – Bikrant Kumar Jul 24 '17 at 18:00
  • Ensure that the host's hostname is configured properly. Ensure that port 7182 is accessible on the Cloudera Manager Server (check firewall rules). Ensure that ports 9000 and 9001 are not in use on the host being added. Check agent logs in /var/log/cloudera-scm-agent/ on the host being added. (Some of the logs can be found in the installation details). – Bikrant Kumar Jul 24 '17 at 18:00
