Subject [jira] [Commented] (YARN-796) Allow for (admin) labels on nodes and resource-requests
Date Mon, 21 Mar 2016 05:06:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15203721#comment-15203721

Naganarasimha G R commented on YARN-796:
----------------------------------------

Yes [~jameszhouyi], in 2.6.0 this command is not yet supported and the documentation which
is available is for 2.7.2 and lot more fixes and features is expected to come in 2.8.0. If
you are planning to experiment this feature then 2.7.2 is fine but to use it in production
then i would suggest to better wait for 2.8.0.
[~wangda], is it required to document what is available as part of 2.6.x ?

> 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.
