----------------------------------
[~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.

> resource types via Yarn APIs?
