Heartbeat failure, while installing the cluster

[#1]

Hi,

 I am getting the below error repeatedly on installing the cluster..

 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.

   Please suggest, how to go forward.

Regards

Can you check iptables is turned off? If yes, Please restart scm agent and try.
