---------------------------------
Summary: 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
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.
