Karthik Kambatla commented on YARN-1012:

For CPU utilization, the other alternative is to send the number of physical 
cores on the machine along with percentage usage (like the one top shows). 

[~vinodkv] - does the need to avoid vcores stem from our intention of moving 
all the utilization information collection to a separate service that might not 
be specific to Yarn?
