             Summary: Components in API should have 'category' field
                 Key: AMBARI-3604
                 URL: https://issues.apache.org/jira/browse/AMBARI-3604
             Project: Ambari
          Issue Type: Bug
            Reporter: Tom Beerbower


Ambari UI when loading services, loads *all* host-components to get service specific metrics, which is available only on master host-components. Loading of client/worker host-components is not needed on dashboard and services pages. 

Hence in API we need a {{type}} field on host_components. This should indicate whether the host_component is master/worker/client/other type. Also, this field should be query-able. 

So the below query should give me services with their master host-components, and their jvm heap metrics.
