[jira] [Created] (YARN-5101) YARN_APPLICATION_UPDATED event is parsed in ApplicationHistoryManagerOnTimelineStore#convertToApplicationReport with reversed order

Xuan Gong created YARN-5101:
-------------------------------

             Summary: YARN_APPLICATION_UPDATED event is parsed in ApplicationHistoryManagerOnTimelineStore#convertToApplicationReport with reversed order
                 Key: YARN-5101
                 URL: https://issues.apache.org/jira/browse/YARN-5101
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.8.0
            Reporter: Xuan Gong


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.
