Subject [jira] [Commented] (YARN-796) Allow for (admin) labels on nodes and resource-requests
Date Thu, 13 Mar 2014 22:47:50 GMT

    [ https://issues.apache.org/jira/browse/YARN-796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13934246#comment-13934246
] 

Arun C Murthy commented on YARN-796:
------------------------------------

[~sandyr] - Sorry, if it wasn't clear. I meant the ACLs for labels should be specified in
each scheduler. 

So, for e.g.:

{noformat}
  <property>
    <name>yarn.scheduler.capacity.root.A.labels</name>
    <value>labelA, labelX</value>
  </property>

  <property>
    <name>yarn.scheduler.capacity.root.B.labels</name>
    <value>labelB, labelY</value>
  </property>
{noformat}

Makes sense?

> 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.
