Tao Yang updated YARN-8945: --------------------------- Attachment: YARN-8945.001.patch > Calculation of maximum applications should respect specified and global > maximum applications for absolute resource > ------------------------------------------------------------------------------------------------------------------ > > Key: YARN-8945 > URL: https://issues.apache.org/jira/browse/YARN-8945 > Project: Hadoop YARN > Issue Type: Bug > Components: capacityscheduler > Affects Versions: 3.2.0 > Reporter: Tao Yang > Assignee: Tao Yang > Priority: Major > Attachments: YARN-8945.001.patch > > > Currently maximum applications is expected to be calculated as follow > according to priority when using percentage based capacity: > (1) equals specified maximum applications for queues > (2) equals global maximum applications > (3) calculated as queue-capacity * maximum-system-applications > But for absolute resource configuration, maximum applications is calculated > as (3) in ParentQueue#deriveCapacityFromAbsoluteConfigurations, this is a > strict limit for high max-capacity and low capacity queues which have little > guaranteed resources but want to use lots of share resources. So I propose to > share the maximum applications calculation of percentage based capacity, > absolute resource can call the same calculation if necessary. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
