Naganarasimha G R updated YARN-2495:
------------------------------------
    Attachment: YARN-2495.20141126-1.patch

Hi [~wangda], corrected the earlier 3 review comments and uploading the patch .

I was going through [YARN-2786] and Vinod had mentioned in one of his [comments|https://issues.apache.org/jira/browse/YARN-2786?focusedCommentId=14203210&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14203210]

IAC, the crux of what you want is a per node script based configuration. That IS happening
as we speak as part of the tickets I referred to. Further, you don't want a central list of
valid labels which I disagree with. *But sure, we will make this configurable to or not to
require a central list so that you can turn it off.* Others like me can turn it on to avoid
random-labels-bubbling-up-in-my-cluster madness.

In this case i feel we need to start discussing on ??YARN-2728 : Support for disabling the
Centralized NodeLabel validation in Distributed Node Label Configuration setup.??
