Subject [jira] [Updated] (YARN-5101) YARN_APPLICATION_UPDATED event is parsed in ApplicationHistoryManagerOnTimelineStore#convertToApplicationReport with reversed order
Date Fri, 08 Jul 2016 16:38:11 GMT

     [ https://issues.apache.org/jira/browse/YARN-5101?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sunil G updated YARN-5101:
--------------------------
    Attachment: YARN-5101.0001.patch

Attaching a patch addressing this issue.
As mentioned earlier, we could check for the time stamp as a reference to identify the latest
event. During appUpdate event, since we are ensuring that all params (queue name, priority)
are updated, we do not need to handle cases like partial updates for one parameter in certain
events.

[~xgong], [~rohithsharma], please help to check the  patch.

> Right now, the application events are parsed in in ApplicationHistoryManagerOnTimelineStore#convertToApplicationReport
with timestamp descending order, which means the later events would be parsed first, and the
previous same type of events would override the information. In
> https://issues.apache.org/jira/browse/YARN-4044, we have introduced YARN_APPLICATION_UPDATED
events which might be submitted by RM multiple times in one application life cycle. This could
cause problem.
