I'm not sure why the NodeStatusUpdate event needs to be generated in all the additional cases. It may just be sufficient to drop the stored node updates - or even let them be processed by the event which is already in the queue. Also, within the schedulers - the events can be aggregated into a single list and processed, instead of processing them per heartbeat. > Each NM heartbeat should not generate and event for the Scheduler > ----------------------------------------------------------------- > > Key: YARN-365 > URL: https://issues.apache.org/jira/browse/YARN-365 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager, scheduler > Affects Versions: 0.23.5 > Reporter: Siddharth Seth > Assignee: Xuan Gong > Attachments: Prototype2.txt, Prototype3.txt, YARN-365.1.patch, YARN-365.2.patch, YARN-365.3.patch, YARN-365.4.patch > > > Follow up from YARN-275 > https://issues.apache.org/jira/secure/attachment/12567075/Prototype.txt -- This message is automatically generated by JIRA.
