Andrew Ferguson commented on MAPREDUCE-4351:
--------------------------------------------

@Bikas, can you say a bit more regarding your comment? I'm not sure what you 
mean. When I implemented the CgroupsContainersMonitor, I didn't find that I was 
reproducing very much code from the DefaultContainersMonitor. Sure, both need 
to initialize the ResourceCalculatorPlugin and use it, but that was about it.

thanks,
Andrew
