Subject [jira] [Commented] (YARN-2012) Fair Scheduler : Default rule in queue placement policy can take a queue as an optional attribute
Date Fri, 02 May 2014 00:18:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-2012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13987205#comment-13987205
] 

Ashwin Shankar commented on YARN-2012:
--------------------------------------

Added an attribute 'queue' to default rule. Also added couple of unit tests.
Patch is expected get -1 from Hadoop QA,since this jira depends upon YARN-1864.

> Currently 'default' rule in queue placement policy,if applied,puts the app in root.default
queue. It would be great if we can make 'default' rule optionally point to a different queue
as default queue . This queue should be an existing queue,if not we fall back to root.default
queue hence keeping this rule as terminal.
> This default queue can be a leaf queue or it can also be an parent queue if the 'default'
rule is nested inside nestedUserQueue rule(YARN-1864).
