Verifying public host name configuration

You can use the Ambari REST API to double-check that Ambari has associated the public host name configured for the Agent.

1. In your web browser, open a new tab.
2. In the new tab Enter the following URL to look at what has been configured for a specific host: http://ambari.server:8080/api/v1/hosts/your.hosts.fqdn
3. Look for 'public_host_name' in the JSON returned from that request to ensure that the correct public host name has been configured for the host in question.
