Karthik Kambatla updated YARN-6210: ----------------------------------- Attachment: YARN-6210.2.patch > FS: Node reservations can interfere with preemption > --------------------------------------------------- > > Key: YARN-6210 > URL: https://issues.apache.org/jira/browse/YARN-6210 > Project: Hadoop YARN > Issue Type: Bug > Components: fairscheduler > Affects Versions: 2.9.0 > Reporter: Karthik Kambatla > Assignee: Karthik Kambatla > Attachments: YARN-6210.1.patch, YARN-6210.2.patch > > > Today, on a saturated cluster, apps with pending demand reserve nodes. A new > app might not be able to preempt resources because these nodes are already > reserved. This can be reproduced by the example in YARN-6151. > Since node reservations are to prevent starvation of apps requesting large > containers, triggering these reservations only on starved applications would > avoid this situation. -- 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
