Naganarasimha G R updated YARN-2495:
------------------------------------
    Attachment: YARN-2495.20141208-1.patch

hi [~wangda],
I have set the default implementation class to be null as per your comment, but 
as you mentioned after review, based on feedback need to set default class with 
either configuration based or script based Node Labels provider as default 
provider class 

> Allow admin specify labels from each NM (Distributed configuration)

> Target of this JIRA is to allow admin specify labels in each NM, this covers
> - User can set labels in each NM (by setting yarn-site.xml (YARN-2923) or 
> using script suggested by [~aw] (YARN-2729) )
> - NM will send labels to RM via ResourceTracker API
> - RM will set labels in NodeLabelManager when NM register/update labels
