Subject [jira] [Commented] (YARN-111) Application level priority in Resource Manager Schedulers
Date Wed, 19 Sep 2012 19:45:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13459016#comment-13459016

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?
