Harsh J commented on YARN-111:
------------------------------
Robert,
I still see Job priority exist in MR1 (1.x). Which JIRA removed this, per your
comment above? Or is this something CapacityScheduler specific we're discussing?
In YARN I see Priority coming in for generally all resource requests (which I
assume does apply to the AM too) and hence
http://hadoop.apache.org/docs/current/api/org/apache/hadoop/yarn/api/records/ApplicationSubmissionContext.html#setPriority(org.apache.hadoop.yarn.api.records.Priority)
ought to work, as the CS's LeafQueue does look at it?
