Based on issues in EPIC looks like only documentation work is remaining in this 
EPIC. Can you address the documentation work and resolve  the EPIC since this 
is part of 2.0.0 release? 

> Add support for "add hosts" with Blueprints API

> Support for "adding hosts" based on *blueprint* style *host_group* via Ambari 
> REST API. There are two scenarios to consider for this JIRA:
> 1) Add hosts based on an existing host in the cluster (and it's *blueprint* 
> style *host_group* component layout). This enables the user to add hosts with 
> components similar to existing hosts in the cluster. For example: expand this 
> cluster with these X hosts and make each of these hosts like Y host 
> (components + configs) existing in the cluster.
> 2) Add hosts based on components + configs. This would be a verbose method 
> that uses *blueprint* style *host_groups* and *configs* to allow you to add 
> hosts to a cluster that do not necessarily have a component layout or config 
> of a similar host existing in the cluster. For example: expand this cluster 
> with these X hosts and make each of these hosts include Y components with Z 
> configs.
