Mahadev konar commented on AMBARI-4467:
---------------------------------------
A couple of comments:
1. The "cardinality" seems a little confusing in the blueprint since it more of
instance related (should show up in manifestation) rather than an abstract
definition. Am not too against it - so we can keep it and see if that helps.
2. On the bp - you need to infer what services are being installed/managed -
might be good to add that to the BP - can be done later.
3. We should make a not of either host_group can be used across blue prints or
should be allow to use blueprint. Its ok to say either but mostly for folks to
know if its possible to use a host group in another bp.

> Key: AMBARI-4467
> URL: https://issues.apache.org/jira/browse/AMBARI-4467
> Project: Ambari
> Issue Type: New Feature
> Reporter: John Speidel
> Assignee: John Speidel
> Labels: api-addition, blueprints
> Fix For: 1.5.0
>
>
> 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}
