Host Registration List
• During Host Registration, if Ambari Agent hosts register that are NOT in your registration list, you will see a warning
• Useful in troubleshooting scenarios where a Host registers with a different hostname than the hostname you specified– Possibly due to DNS and network misconfiguration
