Subject [jira] [Commented] (YARN-5427) Labeled apps cant use <DEFAULT_PARTITION> resources in 2.8
Date Tue, 26 Jul 2016 07:03:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5427?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15393339#comment-15393339

Sunil G commented on YARN-5427:

Hi [~Feng Yuan]

>From 2.8, we will only be able to share resources from a non-exclusive label (exclusivity=false)
to "default" label. Its will not be possible other way around. So any apps which are submitted
without any labels, could be able to share/use resource from a non-exclusive label. So I suggest
you could try defining your system with this node-label model.

>          Issue Type: Bug
>          Components: capacity scheduler
>    Affects Versions: 2.8.0
>            Reporter: Feng Yuan
>             Fix For: 2.8.0
>         Attachments: QQ截图20160725205642.png, capacity-scheduler.xml
> Queue A use partition X,When x is used up,app cant get resource from <DEFAULT_PARTITION>.
> I find this behavior is different from 2.7.x.Also i find this in the document of 2.7.2
as blew:
> "All queues can access to nodes without label"--https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/NodeLabel.html
> I think it means if queue A`s partition x is used up,app can get containers from DEFAULT_PARTITION?
Do i misstake?
> And I can confirm my configs is correct.Because i can run profectlly in 2.7.x use this
configation too.
> I have observed this in 2.8: "<DEFAULT_PARTITION> is marked as <ECLUSIVE_PARTITION>"
in webui.Is this the reason?
