Subject Re: Component placement strategy - Ambari

Thanks Sumit, would dig into the stack advisor bit. 

One more rudimentary question - while setting up the cluster, should the machines be configured
with static IPs (elastic IPs in cloud context) mandatorily or can the machines in the cluster
have dynamic IPs as Ambari considers FQDNs and does the internal mapping between IPs and FQDN?

Regards
Vijay

case any tweaks are required, it would be helpful. For example, if the cluster is being setup
by using Blueprints, what should be the placement guidelines to be considered?
