Sangjin Lee commented on YARN-3995: ----------------------------------- That would be [~vrushalic], not me. :) It might be bit better if we can build this "lingering" functionality at the per-app collector level. Note that we will have an option of running per-app collectors in their own processes. It would be nice if this functionality translates to that mode without much work. Also, note that this linger doesn't need to be too long as we discussed offline. I think 1-2 seconds was more than enough? > Some of the NM events are not getting published due race condition when AM > container finishes in NM > ---------------------------------------------------------------------------------------------------- > > Key: YARN-3995 > URL: https://issues.apache.org/jira/browse/YARN-3995 > Project: Hadoop YARN > Issue Type: Sub-task > Components: nodemanager, timelineserver > Affects Versions: YARN-2928 > Reporter: Naganarasimha G R > Assignee: Naganarasimha G R > Labels: yarn-2928-1st-milestone > > As discussed in YARN-3045: While testing in TestDistributedShell found out > that few of the container metrics events were failing as there will be race > condition.
