Subject [jira] [Commented] (YARN-4074) [timeline reader] implement support for querying for flows and flow runs
Date Mon, 31 Aug 2015 23:35:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14724393#comment-14724393

Li Lu commented on YARN-4074:
-----------------------------

bq. Would there be an appetite for renaming this class to FlowRunEntity as part of this? The
impact should be minimal. Let me know your thoughts.
LGTM. IMO we only have flow run objects, but no actual flow objects? Even in flow-based offline
aggregation we do not instantiate "flow" objects. This JIRA appears to be the right place
to fix it.
