While registering a host to the cluster of Ambari-server, I am getting the following error. "Host checks were skipped on 1 hosts that failed to register." I am trying to install HDP 2.5 version on the instance of AWS. I have tried to follow the documentation of Hortonworks. https://docs.hortonworks.com/HDPDocuments/Ambari-220.127.116.11/bk_ambari-installation/content/set_the_hostname.html I have added public ip address and public hostname to /etc/hosts file and change the name of host in /etc/hostname file on the server and on the host. Rebooted both, hostname got changed. Then I have stop iptables by sudo service iptables stop After doing everything, the host registration is still failing. Kindly help. I am stuck.
