Is it possible to STOP and START a HDP cluster running on Amazon’s EC2? The reason I am asking, is that IP’s of the nodes in the cluster change everytime they are re-started. One possible way may be to use AWS Route53 DNS service to map DNS name to the node’s internal IP address. During the boot process we can create an A record that maps the DNS name to the new internal IP address. The HMC installation will be given the DNS names instead of the internal ip addresses. But is this enough? Do we need to do anything else to configurations of different components like Puppet, Nagios, Ganglia, etc. Has anyone tried this successfully? Is it even possible?
