Error during Cloudera manager 5.16 installation.

[#1]

Hi All, 

I am getting this error during installation anybody got any idea?

 Installation failed. Failed to receive heartbeat from agent.

• 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).
• If Use TLS Encryption for Agents is enabled in Cloudera Manager (Administration → Settings → Security), ensure that /etc/cloudera-scm-agent/config.ini has use_tls=1 on the host being added. Restart the corresponding agent and click the Retry link here.

@Imr This is a generic message if agent installation is failed. Please verify all these things for a quick sanity check. If agent installation still fails then please send the CM server logs:
