Arun Suresh updated YARN-8827: ------------------------------ Attachment: YARN-8827-YARN-1011.04.patch > Plumb per app, per user and per queue resource utilization from the NM to RM > ---------------------------------------------------------------------------- > > Key: YARN-8827 > URL: https://issues.apache.org/jira/browse/YARN-8827 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Arun Suresh > Assignee: Arun Suresh > Priority: Major > Attachments: YARN-8827-YARN-1011.01.patch, > YARN-8827-YARN-1011.02.patch, YARN-8827-YARN-1011.03.patch, > YARN-8827-YARN-1011.04.patch > > > Opportunistic Containers for OverAllocation need to be allocated to pending > applications in some fair manner. Rather than evaluating queue and user > resource usage (allocated resource usage) and comparing against queue and > user limits to decide the allocation, it might make more sense to use a > snapshot of actual resource utilization of the queue and user. > To facilitate this, this JIRA proposes to aggregate per user, per app (and > maybe per queue) resource utilization in addition to aggregated Container and > Node Utilization and send it along with the NM heartbeat. It should be fairly > inexpensive to aggregate - since it can be performed in the same loop of the > {{ContainersMonitorImpl}}'s Monitoring thread. > A snapshot aggregate can be made every couple of seconds in the RM. This > instantaneous resource utilization should be used to decide if Opportunistic > containers can be allocated to an App, Queue or User. -- 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
