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-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
