Wangda Tan commented on YARN-1013: ---------------------------------- Thanks [~haibochen] for explanations, bq. we are trying to just handle G resource requests with their enforcement flag set to false This is the part I don't quite understand, where is the enforcement flag? Is it per app, per request or globally? bq. but the fair scheduler implementation (YARN-1015) tries to take into account of queue weight ... Does this considers resource usages for O container or it is just consider G container usages? > CS should watch resource utilization of containers and allocate speculative > containers if appropriate > ----------------------------------------------------------------------------------------------------- > > Key: YARN-1013 > URL: https://issues.apache.org/jira/browse/YARN-1013 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Arun C Murthy > Assignee: Weiwei Yang > Priority: Major > > CS should watch resource utilization of containers (provided by NM in > heartbeat) and allocate speculative containers (at lower OS priority) if > appropriate. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
