Tom White commented on YARN-333:
--------------------------------
This is not a problem in MR is it, since the queue is always set? But I can see
that it would be needed in general.
The approach looks fine, although I think it would be simpler just to have a
getDefaultQueueName() method on YarnScheduler.
> On app submission, have RM ask scheduler for queue name

> URL: https://issues.apache.org/jira/browse/YARN-333
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.0.2-alpha
> Reporter: Sandy Ryza

>
> Currently, if an app is submitted without a queue, RMAppManager sets the
> RMApp's queue to "default".
> A scheduler may wish to make its own decision on which queue to place an app
> in if none is specified. For example, when the fair scheduler
> user-as-default-queue config option is set to true, and an app is submitted
> with no queue specified, the fair scheduler should assign the app to a queue
> with the user's name.
