Subject [jira] [Commented] (YARN-2738) Add FairReservationSystem for FairScheduler
Date Tue, 04 Nov 2014 01:26:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2738?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14195526#comment-14195526

Subru Krishnan commented on YARN-2738:
--------------------------------------

[~adhoot], I personally prefer per queue configuration and not just for enabling configuration
of org specific agents/policies. I do not believe it adds significant overhead while at the
same time enabling reservation system to run side-by-side existing queue mechanism. It provides
greater flexibility in trying out reservations for only part of the cluster as partitioned
by a leaf queue and in phased migration if required. 

What is the additional complexity between per-queue and system wide settings as we do have
global defaults which should work for majority of the scenarios?
