Subject [jira] [Commented] (YARN-3051) [Storage abstraction] Create backing storage read interface for ATS readers
Date Fri, 27 Mar 2015 21:26:54 GMT

    [ https://issues.apache.org/jira/browse/YARN-3051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14384709#comment-14384709
] 

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 ?

by multiple backing storage implementations.
