Resolution: Fixed
merged to trunk
> Blueprint API: Move host_count and host_predicate fields up one level
> ---------------------------------------------------------------------
>
> Key: AMBARI-11266
> URL: https://issues.apache.org/jira/browse/AMBARI-11266
> Project: Ambari
> Issue Type: Task
> Components: blueprints
> Affects Versions: 2.1.0
> Reporter: John Speidel
> Assignee: John Speidel
> Fix For: 2.1.0
>
>
> Recently, during 2.1 development, API additions were made that allow a host
> count and host predicate to be specified for blueprint provision and scaling
> requests.
> The additions are documented in the Apache Jira:
> https://issues.apache.org/jira/browse/AMBARI-10750
> After some consideration and discussion, it has become clear that the
> host_count and host_predicate fields need to move up one level form their
> current location under hosts. Only explicitly specified hosts will be
> contained within "hosts".
> For example:
> {code}
> {
> "blueprint" : "bp1",
> "host_groups" :[
> {
> "name" : "master",
> "hosts" : [
> {
> "fqdn" : "john2.novalocal"
> }
> ]
> },
> {
> "name" : "slave",
> "host_count" : "5",
> "host_predicate" : "Hosts/cpu_count>1"
> }
> ]
> }
> {code}
