Subject [jira] [Commented] (YARN-3051) [Storage abstraction] Create backing storage read interface for ATS readers
Date Fri, 27 Mar 2015 21:04:53 GMT

    [ https://issues.apache.org/jira/browse/YARN-3051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14384656#comment-14384656
] 

Varun Saxena commented on YARN-3051:
------------------------------------

configs and metrics will be retrieved as part of an entity.
We can filter out which fields to retrieve based on {{EnumSet<Field> fieldsToRetrieve}}.
null means all fields will be retrieved.
So if we do not want all configs and metrics, we can leave them out and mention other fields
in fieldsToRetrieve. This can be mentioned in the REST URL as {{fields=<comma separated
list of fields to be retrieved>}}
