----------------------------------

[~sunilg], 

Thanks for working on the patch, several questions/comments: 

1) Do you think is it a valid use case which client need to maintain their own 
resource-type.xml (different from RM version)? 

2) Is there any issue for client load local resource-types.xml, and overwrite 
it once receive the resource types info from RM?

To me, answers to 1)/2) are all no. I don't think client should keep a 
different version and I don't see any issue if client load resource types first 
and overwrite them by responses from RM. So I think we can avoid add the 
separate config {{load.resource-types.config-file.for-client}} and already load 
{{resource-types.xml}} from classpath.

And should we add resourceTypesInfo to RegisterApplicationMasterResponse? Once 
we have that, we can change AMRMClient to automatically update local resource 
types after register to RM.

> Existing feature requires every client has a resource-types.xml in order to
