Peter Bacsko commented on YARN-9930: ------------------------------------ Created a POC based on the solution exists in FS. No tests yet at all. Note that I copy-pasted {{MaxRunningAppsEnforcer}}. I started to refactor it so that a single class could serve both FS and CS but it just got too big. The class is heavily tied to FS. So I created {{CSMaxRunningAppsEnforcer}}. > Support max running app logic for CapacityScheduler > --------------------------------------------------- > > Key: YARN-9930 > URL: https://issues.apache.org/jira/browse/YARN-9930 > Project: Hadoop YARN > Issue Type: Sub-task > Components: capacity scheduler, capacityscheduler > Affects Versions: 3.1.0, 3.1.1 > Reporter: zhoukang > Assignee: zhoukang > Priority: Major > Attachments: YARN-9930-POC01.patch > > > In FairScheduler, there has limitation for max running which will let > application pending. > But in CapacityScheduler there has no feature like max running app.Only got > max app,and jobs will be rejected directly on client. > This jira i want to implement this semantic for CapacityScheduler. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
