-----------------------------------
Summary: Add setting for default queue in admission controller (was: Add
toggle for adding default queue in admission controller)
> Add setting for default queue in admission controller
> -----------------------------------------------------
>
> Key: YUNIKORN-1650
> URL: https://issues.apache.org/jira/browse/YUNIKORN-1650
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: shim - kubernetes
> Reporter: Mit Desai
> Assignee: Mit Desai
> Priority: Major
> Labels: pull-request-available
>
> If the queue name is not defined during the job submission, YuniKorn
> admission controller will add a default queue to the pod labels.
> When _provided_ placement rule is defined, along with other placement rules,
> it is possible that only provided placement rule is executed and no other
> rule is exercised.
> In the following scenario, when there are 3 placement rules defined,
> placementrules:
> - name: provided
> - name: tag
> - name: fixed
> The applications will be placed in the right queue, following the _provided_
> rule if the queue is defined during job submission. If the queue is not
> defined during job submission, admission controller will add a default queue
> name. This will again trigger the provided rule as the queue name will be
> found in the pod labels during placement rules execution. As a result, _tag_
> and _fixed_ rules will never be executed and all the apps that do not have a
> queue defined will end up getting placed in the default queue.
> To solve this, we should have a toggle in the admission controller configs
> whether to add the default queue to or not. Whenever such placement rules are
> setup, admission controller should be configured to skip adding the default
> queue name.
