Subject [jira] [Commented] (YARN-2696) Queue sorting in CapacityScheduler should consider node label
Date Wed, 08 Apr 2015 20:38:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-2696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14485965#comment-14485965
] 

Wangda Tan commented on YARN-2696:
----------------------------------

[~cwelch],
For example, when a node with label=x doing heartbeat, we need sort children queues by usage
*of label=x*. Now behavior is sort children queues always by usage *of NO-LABEL*, which is
not correct.

> Queue sorting in CapacityScheduler should consider node label

> In the past, when trying to allocate containers under a parent queue in CapacityScheduler.
The parent queue will choose child queues by the used resource from smallest to largest. 
> Now we support node label in CapacityScheduler, we should also consider used resource
in child queues by node labels when allocating resource.
