-----------------------------------------
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}}
> Running applications information changes such as movequeue is not published
> to TimeLine server
