Created subclass AppLevelTimelineCollectorWithAgg that handles the thread related agg stuff. Creating this class in the NM and keeping the earlier AppLevelTimelineCollector class in RM. > Refactor AppLevelTimelineCollector such that RM does not have aggregator > threads created > ---------------------------------------------------------------------------------------- > > Key: YARN-6888 > URL: https://issues.apache.org/jira/browse/YARN-6888 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Reporter: Vrushali C > Assignee: Vrushali C > Attachments: YARN-6888-YARN-5355.0001.patch > > > Currently both RM and NM use the same AppLevelTimelineCollector class. The NM > requires aggregator threads per application so that it can perform in memory > aggregation for application metrics but the RM does not need this. Since they > share the code, RM has a bunch of "TimelineCollector Aggregation" threads > created (one per running app). > Filing jira to refactor AppLevelTimelineCollector such that RM does not have > aggregator threads created. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
