Subject [jira] [Commented] (YARN-796) Allow for (admin) labels on nodes and resource-requests
Date Fri, 14 Mar 2014 20:38:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13935594#comment-13935594
] 

Alejandro Abdelnur commented on YARN-796:
-----------------------------------------

scheduler configurations are refreshed dynamically, if the list of valid labels is there,
it could be refreshed as well. i would prefer to detect & reject typos from a user experience
and troubleshooting point of view.

> 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.
