Tom Beerbower commented on AMBARI-3604:
---------------------------------------
Exposing a new property on the component resource ...
* ServiceComponentInfo/category
It has the following possible values
# MASTER
# SLAVE
# CLIENT
You can query for all MASTER components like this ...
{code}
api/v1/clusters/c1/components/?ServiceComponentInfo/category=MASTER
{code}
You can query for all of the master components, and their host component jvm
heap metrics like this ...
{code}
api/v1/clusters/c1/components/?ServiceComponentInfo/category=MASTER&fields=ServiceComponentInfo,host_components,host_components/HostRoles,host_components/metrics/jvm/memHeapUsedM
{code}
> Components in API should have 'category' field

> Project: Ambari
> Issue Type: Bug
> Reporter: Tom Beerbower
> Assignee: 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.
