Subject [jira] [Commented] (YARN-3903) Disable preemption at Queue level for Fair Scheduler
Date Wed, 22 Jul 2015 03:52:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-3903?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14636173#comment-14636173

He Tianyi commented on YARN-3903:
---------------------------------

The latter one.
I encountered the requirement that needs to prevent particular jobs from being preempted.
This can either be done at queue-level or job-level. IMHO queue level have the advantage of
transparency over job-level.
