[jira] [Updated] (YARN-471) NM does not validate the resource capabilities before it registers with RM

["Vinod Kumar Vavilapalli (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-471?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vinod Kumar Vavilapalli updated YARN-471:
-----------------------------------------

    Component/s:     (was: resourcemanager)
                 nodemanager
        Summary: NM does not validate the resource capabilities before it registers with RM  (was: RM does not validate the resource capability of an NM when the NM registers with the RM)

Because NM and RM both are the trusted components in the system, I think we should do this validation on the NM itself.

Modifying the description, please revert it if you disagree.
