ChenFolin created YARN-4980: ------------------------------- Summary: SchedulerEventDispatcher should not process by only a single EventProcessor thread Key: YARN-4980 URL: https://issues.apache.org/jira/browse/YARN-4980 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Affects Versions: 2.6.4, 2.5.0 Environment: 1 resourcemanager 500 nodemanager nodemanager heartbeat interval is 3 secs.
Reporter: ChenFolin I think only a single EventProcessor thread in SchedulerEventDispatcher to process event is unreasonable. I often see "Size of scheduler event-queue is 1000(2000..)..." at the resourcemanager log. Now I have 500 nodemanager , event process is slowly. If I add another 200 nodemanagers , the situation will badly. ... so,can node events(node add/delete/update...) processed by multi threads? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
