      Description

      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.
