--------------------------------------
Sorry for the lack of formatting in my previous comment, I don't have
privileges to edit my post :(
Here are the same examples formatted.
Case 1: specify an existing host that will be "cloned" with regards to
components/configuration
{code}
"host_groups" : [
{
"hosts" : [
{
"fqdn" : "192.168.1.2"
},
{
"fqdn" : "192.168.1.3"
}
],
"host_to_clone" : "existingHost.foo.com"
}
]
{code}
Case 2: Specify a blueprint/hostgroup from which to obtain the component set
for the new host(s)
{code}
"host_groups" : [
{
"hosts" : [
{
"fqdn" : "192.168.1.2"
},
{
"fqdn" : "192.168.1.3"
}
],
"blueprint" : "myBlueprint",
"host_group" : "slaves"
}
]
{code}

> 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.
