["Wangda Tan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13958434#comment-13958434 ] 

Wangda Tan commented on YARN-796:
---------------------------------

[~acmurthy], thanks for this patch, I’ve a few questions/suggestions for this implementation. Please forgive the ignorance if my suggestion makes no sense.
1. Is it good to put SchedulerLabelsManager.add/removeNode invoke to RMNodeImpl transition, which can be leveraged by CS/FS at the same time?
2. I’m wondering does it make sense to put SchedulerLabelsManager into RMContext?
3. Do we need consider labels of queue/application (not RR) will affect headroom of an application? (If yes, we need consider linking this to YARN-1198).
Thanks,

> It will be useful for admins to specify labels for nodes. Examples of labels are OS, processor architecture etc.
> We should expose these labels and allow applications to specify labels on resource-requests.
> Obviously we need to support admin operations on adding/removing node labels.
