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.
