[jira] [Commented] (YARN-2257) Add user to queue mapping in Fair-Scheduler

The configuration can be per scheduler. I propose we fix it in general. Will edit the subject if there is no disagreement. > Add user to queue mapping in Fair-Scheduler > --- > > Key: YARN-2257 > URL: https://issues.apache.org/jira/browse/YARN-2257 > Project: Hadoop YARN > Issue Type: Improvement > Components: scheduler >Reporter: Patrick Liu > Labels: features > > Currently, the fair-scheduler supports two modes, default queue or individual > queue for each user. > Apparently, the default queue is not a good option, because the resources > cannot be managed for each user or group. > However, individual queue for each user is not good enough.
