Subject [jira] [Updated] (YARN-5101) YARN_APPLICATION_UPDATED event is parsed in ApplicationHistoryManagerOnTimelineStore#convertToApplicationReport with reversed order
Date Thu, 14 Jul 2016 06:57:20 GMT

Sunil G updated YARN-5101:

    Attachment: YARN-5101.0002.patch

Thanks [~rohithsharma]. It makes sense.
Updated a patch with this approach, however {{SystemClock}} was used by {{RMAppImpl}} which
is internally using {{System.currentTimeMillis}} and it was available only in RMAppImpl, so
CS#updateApplicationPriority had to use old approach. I will raise a separate jira to use
MonotonicClock for RMAppImpl.

> 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.
