Andrew Wang updated YARN-6193: ------------------------------ Fix Version/s: 3.0.0-alpha3 > FairScheduler might not trigger preemption when using DRF > --------------------------------------------------------- > > Key: YARN-6193 > URL: https://issues.apache.org/jira/browse/YARN-6193 > Project: Hadoop YARN > Issue Type: Sub-task > Components: fairscheduler > Affects Versions: 2.8.0 > Reporter: Karthik Kambatla > Assignee: Karthik Kambatla > Fix For: 2.9.0, 3.0.0-alpha3 > > Attachments: YARN-6193.000.patch, YARN-6193.001.patch, > YARN-6193.002.patch, YARN-6193.003.patch > > > {{FSAppAttempt#canContainerBePreempted}} verifies preempting a container > doesn't lead to new starvation ({{Resources.fitsIn}}). When using DRF, this > leads to verifying both resources instead of just the dominant resource. > Ideally, the check should be based on policy. > Note that current implementation of > {{DominantResourceFairnessPolicy#checkIfUsageOverFairShare}} is broken. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
