Varun Saxena commented on YARN-3051:
------------------------------------
For the point about shallow view of entity, we can then say if
{{fieldsToRetrieve}} is null i.e. client does not specify which fields to
retrieve, store implementation will return all fields except configs and
metrics.
I can add another special field called "all" which would indicate all fields
will have to be retrieved. So if client specifies fields=all in REST URL,
storage implementation will fetch all the fields. Thoughts ?
