Wangda Tan commented on YARN-2004:
----------------------------------
Thanks for updating, [~sunilg].
A quick comment before posting others, I think most of the code to check/update
application priority can be reused by other schedulers. [~kasha], could you
take a quick look at this patch to see if it is also needed for Fair Scheduler?

> Based on the priority of the application, Capacity Scheduler should be able
> to give preference to application while doing scheduling.
> Comparator<FiCaSchedulerApp> applicationComparator can be changed as below.
>
> 1. Check for Application priority. If priority is available, then return
> the highest priority job.
> 2. Otherwise continue with existing logic such as App ID comparison and
> then TimeStamp comparison.
