Jeff Sposetti commented on AMBARI-8458:
---------------------------------------

1) Created a simple blueprint that includes a master host group and worker host group, using HDP 2.2 Stack:

{code}
POST http://c6401.ambari.apache.org:8080/api/v1/blueprints/single-node-hdfs-yarn
{
  "host_groups" : [
    {
      "name" : "master",
      "components" : [
      {
        "name" : "NAMENODE"
      },
      {
        "name" : "SECONDARY_NAMENODE"
      },
      {
        "name" : "DATANODE"
      },
      {
        "name" : "HDFS_CLIENT"
      },
      {
        "name" : "RESOURCEMANAGER"
      },
      {
        "name" : "NODEMANAGER"
      },
      {
        "name" : "YARN_CLIENT"
      },
      {
        "name" : "HISTORYSERVER"
      },
      {
        "name" : "MAPREDUCE2_CLIENT"
      },
      {
        "name" : "ZOOKEEPER_SERVER"
      },
      {
        "name" : "APP_TIMELINE_SERVER"
      },
      {
        "name" : "ZOOKEEPER_CLIENT"
      }
      ],
      "cardinality" : "1"
    },
    {
      "name" : "worker",
      "components" : [
      {
        "name" : "DATANODE"
      },
      {
        "name" : "HDFS_CLIENT"
      },
      {
        "name" : "NODEMANAGER"
      },
      {
        "name" : "YARN_CLIENT"
      }
      ],
      "cardinality" : "1+"
    }
  ],
  "Blueprints" : {
    "blueprint_name" : "single-node-hdfs-yarn",
    "stack_name" : "HDP",
    "stack_version" : "2.2"
  }
}
{code}

2) Manually registered Ambari Agent host c6403.ambari.apache.org to Ambari Server:

3) Add that host to the cluster:

{code}
POST http://c6401.ambari.apache.org:8080/api/v1/clusters/MyCluster/hosts/c6403.ambari.apache.org

{
    "blueprint" : "single-node-hdfs-yarn",
    "host_group" : "worker"
}
{code}

4) Alternatively, if you want to add > 1 host at a single time, you can use this syntax (be sure all hosts are already registered manually with Ambari Server):

{code}
POST http://c6401.ambari.apache.org:8080/api/v1/clusters/MyCluster/hosts

[
{
    "blueprint" : "single-node-hdfs-yarn",
    "host_group" : "worker",
    "host_name" : "c6403.ambari.apache.org"
},
{
    "blueprint" : "single-node-hdfs-yarn",
    "host_group" : "worker",
    "host_name" : "c6404.ambari.apache.org"
}
]
{code}

> Provide a higher level api for host provisioning.
> This api will accept a host name, blueprint name and host group.
> The result of this api call will be fully operational hosts added to the existing cluster with configuration and components which are defined in the specified blueprint/host_group.  All components on the added hosts will be installed and started.
> All hosts must be reachable via ambari server and have the ambari agent running and registered with the ambari server prior to using this api.  
> This is an asynchronous api so it will return the standard asynchronous response.
