Thanks [~leftnoteasy]]
No, you can update current trunk code, and check 
RMContainerImpl#FinishedTransition#updateMetricsIfPreempted, you can change the 
"updateMetricsIfPreempted" to something like updateAttemptMetrics. And create a 
new method in RMAppAttemptMetrics, like "updateResourceUtilization". The 
benefit of doing this is you don need send payload to RMAppAttempt, all you 
needed information should be existed in RMContainer.

updateMetricsIfPreempted() is using the current attempt. Is there a way to get 
the RMAppAttempt object for completed attempts. IIUC, there are races where 
there is no running attempt, such as when an attempt dies after other 
containers have started and then the app itself dies or is killed. Also, in the 
case of "work-preserving restart," the appattempt could die and it's child 
containers could be assigned to the second appattempt,

I have included a new patch that adds the payload to the CONTAINER_FINISHED 
event, which is sent to the appropriate RMAppAttempt. The RMAppAttempt then 
will keep track of it's own stats, even after the container for that appattempt 
has finished.

> For the purpose of chargeback, I'd like to be able to compute the cost of an
> application in terms of cluster resource usage.  To start out, I'd like to 
> get the memory utilization of an application.  The unit should be MB-seconds 
> or something similar and, from a chargeback perspective, the memory amount 
> should be the memory reserved for the application, as even if the app didn't 
> use all that memory, no one else was able to use it.
> (reserved ram for container 1 * lifetime of container 1) + (reserved ram for
> container 2 * lifetime of container 2) + ... + (reserved ram for container n 
> * lifetime of container n)
> It'd be nice to have this at the app level instead of the job level because:
> 1. We'd still be able to get memory usage for jobs that crashed (and wouldn't 
> appear on the job history server).
> 2. We'd be able to get memory usage for future non-MR jobs (e.g. Storm).
> This new metric should be available both through the RM UI and RM Web 
> Services REST API.
