Nate Cole commented on AMBARI-5004:
-----------------------------------
YARN metainfo.xml defines two services, which means that each service will load
the properties in the configuration directory. In this case, YARN and
MAPREDUCE2 will have matching config names.
> Many YARN configs are duplicated in MR2 configs

> Now MR2 and YARN share the same folder in stacks/HDP/2.1.1/services/YARN, and
> a lot of (more than 50) YARN configs existed in MR2 service too.
> eg. {code}
> GET /api/v1/stacks2/HDP/versions/2.1.1/stackServices/MAPREDUCE2,{code} there
> are properties like {code}yarn.resourcemanager.resource-tracker.address{code}
> ,etc.
> So these config properties should show up for YARN ONLY.
