[jira] [Commented] (YARN-306) FIFO scheduler doesn't respect changing job priority
[ https://issues.apache.org/jira/browse/YARN-306?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14790676#comment-14790676 ] Rohith Sharma K S commented on YARN-306: Agree for on-demand implementing priority support in FIFO scheduler. And work around also exist with CS. Sorry I did not give my full thoughts on violating FIFO scheduling policy what it by means. In CS, choosing of queues at the same level is based on the sorted order of child Queues by used-capacity. If used capacity is same across the queues then sorted using guaranteed capacity. At leafQueue level, FIFO policy is used which is changed now with priority as first. Basically CS tries to choose the queue's at same level by capacity but in FIFO scheduler there is no queue concept, applications are assigned in FIFO order. In CS, fifo policy at leaf queue is violated which is one part of CS, where as FIFO scheduler will be violating fully if priority supports. > FIFO scheduler doesn't respect changing job priority > > > Key: YARN-306 > URL: https://issues.apache.org/jira/browse/YARN-306 > Project: Hadoop YARN > Issue Type: Sub-task > Components: scheduler >Affects Versions: 2.0.2-alpha >Reporter: Nishan Shetty >Assignee: Rohith Sharma K S > > 1.Submit job > 2.Change the job priority using setPriority() or CLI command ./mapred > job-set-priority > Observe that Job priority is not changed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

Thinking that it may violate FIFO scheduling policy.
