Karthik Kambatla commented on YARN-3122:
----------------------------------------
[~venkateshrin] - thanks for chiming in.
Given that ResourceCalculatorProcessTree was @Private, I was okay with
including an abstract method. As [~hitesh] points on YARN-3296, I understand
why we would want to make it @Public. Let us continue the conversation there.

> It would be nice to capture resource usage per container, for a variety of
> reasons. This JIRA is to track CPU usage.
> YARN-2965 tracks the resource usage on the node, and the two implementations
> should reuse code as much as possible.
