> Add user to queue mappings to automatically place users' apps into specific
> queues
> ----------------------------------------------------------------------------------
>
> Key: YARN-2257
> URL: https://issues.apache.org/jira/browse/YARN-2257
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: scheduler
> Reporter: Patrick Liu
> Assignee: Vinod Kumar Vavilapalli
> 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. Especially when
> connecting yarn with hive. There will be increasing hive users in a corporate
> environment. If we create a queue for a user, the resource management will be
> hard to maintain.
> I think the problem can be solved like this:
> 1. Define user->queue mapping in Fair-Scheduler.xml. Inside each queue, use
> aclSubmitApps to control user's ability.
> 2. Each time a user submit an app to yarn, if the user has mapped to a queue,
> the app will be scheduled to that queue; otherwise, the app will be submitted
> to default queue.
> 3. If the user cannot pass aclSubmitApps limits, the app will not be accepted.
