zhengchenyu created YARN-5919: --------------------------------- Summary: FairSharePolicy is not reasonable when sorting the application Key: YARN-5919 URL: https://issues.apache.org/jira/browse/YARN-5919 Project: Hadoop YARN Issue Type: Improvement Components: yarn Affects Versions: 2.7.1 Environment: CentOS-7.1 Reporter: zhengchenyu Priority: Critical Fix For: 2.7.1
I use the FairSharePolicy to sort the runnableApps in FSLeafQueue. For the comparation of FSAppAttempt, s1Needy and s1Needy must be negtive. So FairSharePolicy will use useToWeightRatio to compare. This algorithm only consider the ResourceUsage of the FSAppAttempt. There is a unreasonable phenomenon: A low ResourceUsage FsAppAttemp with no demand(or request) will be in front of the queue, then skip this chance of assigning container. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
