Subject [jira] [Created] (AMBARI-1401) Provide API support for querying sub-resources
Date Tue, 12 Feb 2013 18:57:13 GMT
John Speidel created AMBARI-1401:
------------------------------------

             Summary: Provide API support for querying sub-resources
                 Key: AMBARI-1401
                 URL: https://issues.apache.org/jira/browse/AMBARI-1401
             Project: Ambari
          Issue Type: Sub-task
            Reporter: John Speidel
            Assignee: John Speidel
             Fix For: 1.3.0


Currently, query predicates can only be applied to the top level resource of a request.  So,
if we wanted to perform a query based on sub-resource state, this would require multiple requests.

For example, to query for all services which contain a component in any state other than "STARTED":

.../api/v1/clusters/c1/services?components/ServiceComponentInfo/state!=STARTED

Because the above request applies a predicate to a sub-resource of service(component), this
is not currently supported. The goal of this Jira is to allow predicates to be applied to
any sub-resource, in addition to the the top level resource of any request.
