Subject [jira] [Commented] (YARN-6439) Fix ReservationSystem creation of default ReservationQueue
Date Tue, 04 Apr 2017 23:34:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-6439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15956054#comment-15956054
] 

Carlo Curino commented on YARN-6439:
------------------------------------

The v0 patch was failing in FairScheduler version of tests, as in FS we do not pre-create
the defaultQueue. I believe in FS we do not ever create the default queue. This is implicitly
done when an application is submitted to the plan queue without a reservationId. Hence in
the tests I checked differently the behavior.

> The ReservationSystem does not create the default ReservationQueue till the PlanFollower
runs the first time. This is problematic for SLS runs, and might show up in some other corner
case. Inlining creation of the queue as part of PlanQueue creation.
