[jira] [Commented] (AMBARI-4467) Create new /blueprints REST endpoint

["Eric Yang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-4467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13887565#comment-13887565 ] 

Eric Yang commented on AMBARI-4467:
-----------------------------------

In Ambari-1783, the proposal was having components then hosts because hadoop services are applying one component/service across multiple host groups.  In this proposal, it is doing traditional mapping of host group > components.  This is more difficult to manage for orchestrating cross node components/services.

> Create a new /blueprints REST endpoint. This endpoint represents an 'abstract blueprint' or 'template' and doesn't contain cluster specific details such specific host information.
> This initial jira will be limited to basic blueprint information and will not contain configuration elements.  These additional elements will be added in subsequent patches.
> Available operations are get, create and delete.  Update is not supported because blueprints are immutable.
> Example of a simple blueprint resource:
> {code}
> {
>   "href" : "http://172.18.193.10:8080/api/v1/blueprints/bp1",
>   "host_groups" : [
>     {
>       "name" : "foo",
>       "components" : [
>         {
>           "name" : "component2"
>         },
>         {
>           "name" : "component1"
>         },
>         {
>           "name" : "component4"
>         },
>         {
>           "name" : "component3"
>         }
>       ],
>       "cardinality" : "2"
>     },
>     {
>       "name" : "bar",
>       "components" : [
>         {
>           "name" : "component5"
>         }
>       ],
>       "cardinality" : "1"
>     }
>   ],
>   "Blueprints" : {
>     "blueprint_name" : "bp1",
>     "stack_name" : "HDP",
>     "stack_version" : "1.3.3"
>   }
> }
> {code}
