Craig Welch updated YARN-3510:
    Attachment: YARN-3510.6.patch

Ran all of the tests listed as failing or timing out on my box with the patch 
and the all pass, must be a build server issue or something of that nature.  
Clicking on the findbugs link indicates that there are no findbugs issues (0 
listed), is there something wrong with the feedback process?  Fixed all of the 
checkstyle issues except one which I don't think is important.

> The ProportionalCapacityPreemptionPolicy preempts as many containers from 
> applications as it can during it's preemption run.  For fifo this makes 
> sense, as it is prempting in reverse order & therefore maintaining the 
> primacy of the "oldest".  For fair ordering this does not have the desired 
> effect - instead, it should preempt a number of containers from each 
> application which maintains a fair balance /close to a fair balance between 
> them
