Akhil PB commented on YARN-8711:
--------------------------------
Hi [~suma.shivaprasad], Could you please provide which API gives the state of
the components?
We are displaying the service state in the service info page. But the states
are not available for the service components from the API itself.
For example: The component API
{{http://localhost:8198/ws/v2/timeline/clusters/yarn-cluster/apps/application_1548064352792_0002/entities/COMPONENT?fields=ALL&type=COMPONENT&_=1548065347971}}
gives

There is no state info available in the info object.
And component instances are displayed with states in the table.
