Arun Suresh updated YARN-5350: ------------------------------ Attachment: YARN-5350.002.patch Updating patch with checkstyle fix. The test failure is spurious... > Ensure LocalScheduler does not lose the sort order of allocatable nodes > returned by the RM > ------------------------------------------------------------------------------------------ > > Key: YARN-5350 > URL: https://issues.apache.org/jira/browse/YARN-5350 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Arun Suresh > Assignee: Arun Suresh > Fix For: 2.9.0 > > Attachments: YARN-5350.001.patch, YARN-5350.002.patch > > > The LocalScheduler receives an ordered list of nodes from the RM with each > allocate call. This list, which is used by the LocalScheduler to allocate > OPPORTUNISTIC containers, is sorted on the Nodes free capacity (queue length > / wait time). > Unfortunately, the LocalScheduler stores this list in a HashMap thereby > losing the sort order. > The trivial fix would be to replace the HashMap with a LinkedHashMap which > retains the insertion order. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
