Sunil G created YARN-2004:
-----------------------------

             Summary: Job Priority scheduling support in Capacity scheduler
                 Key: YARN-2004
                 URL: https://issues.apache.org/jira/browse/YARN-2004
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: capacityscheduler
            Reporter: Sunil G


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.
