Subject [jira] [Commented] (YARN-4074) [timeline reader] implement support for querying for flows and flow runs
Date Thu, 17 Sep 2015 18:19:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-4074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14803340#comment-14803340
] 

Sangjin Lee commented on YARN-4074:
-----------------------------------

That's correct. In other words, those are used to do {{getEntity()}}. That's why I said "a
reader for *single-entity reads*" (plural "reads"), as opposed to "a reader for a single entity
read".
