Hi @suresh krish

You can use the Ambari REST API to add new hosts, and deploy services (such as DATANODE on the hosts). See the documentation here for the steps: https://cwiki.apache.org/confluence/display/AMBARI/Add+a+host+and+deploy+components+using+APIs

Ambari registration on the new datanode which we cannot be automated. ??
