Sandy Ryza commented on YARN-2072:
----------------------------------

In the Fair Scheduler web page we report every resource as a vector with both 
CPU and memory.

The Fair Scheduler actually always enforces vcore node limits and uses the 
number of vcores in the request for respecting these - what's configurable is 
whether fairness decisions get based on both CPU and memory or just memory.


> RM/NM UIs and webservices are missing vcore information
