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

Thanks [~leftnoteasy] for reviewing the patch.

Thanks [~ellenfkh] for the patch. It mostly LGTM, just a couple of minor 
comments:
  * Can you add a *YARN_FEDERATION_PREFIX* in {{YarnConfiguration}} as we are 
going to be using it a lot more in subsequent JIRAs.
  * Please add findbugs exclusion for {{nodes}} and {{nodes-malformed}} test 
resources.
  * I feel the checkstyle warnings are not blockers but will good to fix if 
it's easy to do so.

> This JIRA tracks effort to create a mechanism to resolve nodes/racks resource 
> names to sub-cluster identifiers. This is needed by the federation policies 
> in YARN-5323, YARN-5324, YARN-5325 to operate correctly.
