Subject [jira] [Commented] (YARN-4044) Running applications information changes such as movequeue is not published to TimeLine server
Date Thu, 03 Sep 2015 07:52:47 GMT

    [ https://issues.apache.org/jira/browse/YARN-4044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14728639#comment-14728639

Naganarasimha G R commented on YARN-4044:
-----------------------------------------

Hi [~sunilg], IIUC intention of this jira is to show in the ATS UI with the modifed queue
or priority if any right ?. If so it requires modification in {{ApplicationHistoryManagerOnTimelineStore.convertToApplicationReport}}
needs to capture the event {{ApplicationMetricsConstants.UPDATED_EVENT_TYPE}} and update the
ApplicationReport object. At the same time we need to ensure that if multiple application
updates are done then we need to show the latest update in the UI. As per the logic what i
 see in {{LeveldbTimelineStore.getEntity(String, String, Long, EnumSet<Field>, LeveldbIterator,
byte[], int)}} seems like all the events are captured and returned in which case we need to
check return the report with the information present in latest {{ApplicationMetricsConstants.UPDATED_EVENT_TYPE}}
