Arun Suresh commented on YARN-7258: ----------------------------------- +1 for the latest patch. Committed this to trunk. Thanks for the patch [~kartheek] > Add Node and Rack Hints to Opportunistic Scheduler > -------------------------------------------------- > > Key: YARN-7258 > URL: https://issues.apache.org/jira/browse/YARN-7258 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Arun Suresh > Assignee: kartheek muthyala > Attachments: YARN-7258.001.patch, YARN-7258.002.patch, > YARN-7258.003.patch, YARN-7258.004.patch > > > Currently, the Opportunistic Scheduler ignores the node and rack information > and allocates strictly on the least loaded node (based on queue length) at > the time it received the request. This JIRA is to track changes needed to > allow the OpportunisticContainerAllocator to take the node/rack name as hints. > The flow would be: > # If requested node found in the top K leastLoaded nodes, allocate on that > node > # Else, allocate on least loaded node on the same rack from the top K least > Loaded nodes. > # Else, allocate on least loaded node. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
