Karthik Kambatla commented on YARN-3547: ---------------------------------------- In FSAppAttempt, pending resources can be derived from {{getDemand() - getResourceUsage()}}. Can we use that please? > FairScheduler: Apps that have no resource demand should not participate > scheduling > ---------------------------------------------------------------------------------- > > Key: YARN-3547 > URL: https://issues.apache.org/jira/browse/YARN-3547 > Project: Hadoop YARN > Issue Type: Improvement > Components: fairscheduler > Reporter: Xianyin Xin > Assignee: Xianyin Xin > Attachments: YARN-3547.001.patch, YARN-3547.002.patch, > YARN-3547.003.patch, YARN-3547.004.patch > > > At present, all of the 'running' apps participate the scheduling process, > however, most of them may have no resource demand on a production cluster, as > the app's status is running other than waiting for resource at the most of > the app's lifetime. It's not a wise way we sort all the 'running' apps and > try to fulfill them, especially on a large-scale cluster which has heavy > scheduling load. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
