Daniel Templeton commented on YARN-6028:
----------------------------------------

Thanks, [~cheersyang]!  Much needed doc.  A few comments:

* Milliseconds is "ms".  "MS" is mega-Siemens
* "vcore usages" should be "vcores used" throughout
* "Total number of physical memory" should be "Total amount of physical memory" 
throughout
* I think "usage[s]" can be globally replaced with "used".  A "usage" is a 
single event, so if I used 16 vcores once, that's 1 _usage_ with 16 vcores 
_used_.
