Sunil G commented on YARN-5295:
-------------------------------
Thanks [~Prabhu Joseph] for the clarification.
Yes, we select a queue and then we do sanity after that. And if sanity check
(validations) fails for this selected queue, we will reject the app submission.
In this given scenario, may be a group configuration seems valid and the jira
is focussing on that point. Got it. +1 for the approach.
Interestingly we need to see how 3rd point is to be handled {{3. is user either
have ACL Submit_Applications or Administer_Queue of the queue.}}, we may
possibly relax some ACLs here if we do that. If a user (user *test*) is not
given permission to queue (queue named *test* in this context), and same user's
group (group *edw*) has permission in another queue (queue named *platform* in
this context), I think we have to give preference for user than group. So i
think current implementation holds good for 3rd point. Thoughts?
> YARN queue-mappings to check Queue is present before submitting job
> -------------------------------------------------------------------
>
> Key: YARN-5295
> URL: https://issues.apache.org/jira/browse/YARN-5295
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacity scheduler
> Affects Versions: 2.7.2
> Reporter: Prabhu Joseph
>
> In yarn Queue-Mappings, Yarn should check if the queue is present before
> submitting the job. If not present it should go to next mapping available.
> For example if we have
> yarn.scheduler.capacity.queue-mappings=u:%user:%user,g:edw:platform
> and I submit job with user "test" and if there is no "test" queue then it
> should check the second mapping (g:edw:platform) in the list and if test is
> part of edw group it should submit job in platform queue.
> Below Sanity checks has to be done for the mapped queue in the list and if it
> fails then the the next queue mapping has to be chosen, when there is no
> queue mapping passing the sanity check, only then the application has to be
> Rejected.
> 1. is queue present
> 2. is queue not a leaf queue
> 3. is user either have ACL Submit_Applications or Administer_Queue of the
> queue.
