Colin Patrick McCabe commented on YARN-1747:
--------------------------------------------
My first thought here is to read /proc/<pid>/maps and look for the [stack] and
[heap] sections, and just count those. There might be something I'm not
considering, though. I wonder if there is ever a case where we'd want to
charge an application for the page cache its use of a file takes up?
> Better physical memory monitoring for containers
