Subject [jira] [Commented] (YARN-3051) [Storage abstraction] Create backing storage read interface for ATS readers
Date Fri, 27 Mar 2015 22:12:55 GMT

    [ https://issues.apache.org/jira/browse/YARN-3051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14384785#comment-14384785
] 

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

Just to elaborate further, below API will be used to serve the use case above.
{code}
  TimelineEntity getEntity(String entityId, String entityType,
      EnumSet<Field> fieldsToRetrieve)
{code}
Assuming entityid will be same as appid if entity type is "application", we can fetch configs
for application_12345_0001 like below :
{{http://<base url>/application/application_12345_0001?fields=configs}}
