[jira] [Commented] (YARN-4074) [timeline reader] implement support
for querying for flows and flow runs
[ 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.
