Arun Suresh created YARN-5350: --------------------------------- Summary: 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
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-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
