> Key: YUNIKORN-2504
> URL: https://issues.apache.org/jira/browse/YUNIKORN-2504
> Project: Apache YuniKorn
> Issue Type: Sub-task
> Components: core - scheduler, release-notes, shim - kubernetes
> Reporter: Yu-Lin Chen
> Assignee: Yu-Lin Chen
> Priority: Major
> Labels: pull-request-available, release-notes
> Fix For: 1.6.0

> Currently, we support queue/applicationID set in both label and annotation.
> Queue
> * queue [label] → {color:#de350b}If set, ignore annotation’s value{color}
> * yunikorn.apache.org/queue [annotation]
> ApplicationID
> * applicationId [label]
> * yunikorn.apache.org/app-id [annotation] → {color:#de350b}If set, ignore
> label’s value{color}
> According to the new policy defined in YUNIKORN-1351.
> We will add *canonical representation* to Queue/ApplicationId:
> * yunikorn.apache.org/queue [label]
> * yunikorn.apache.org/app-id [label]
> Also align the ordering when fetch app-id/queue from pod:
> app-id should be fetched in below order:
> # Label: yunikorn.apache.org/app-id ({*}New{*})
> # Annotation: yunikorn.apache.org/app-id
> # Label: applicationId
> # Label: spark-app-selector
> queue name should be fetched in below order:
> # Label: yunikorn.apache.org/queue ({*}New{*})
> # Annotation: yunikorn.apache.org/queue
> # Label: queue
>
> Non-canonical format will be kept for backward compatibility.
> However, If the same metadata (queue or applicationID) is specified in
> multiple locations and their values are inconsistent, the admission
> controller and scheduler should reject the pod. ({*}Version 1.6.0 only prints
> out warnings; task rejection should occur in version 1.7.0{*}.) This change
> is tracked by YUNIKORN-2810 and YUNIKORN-2811.
>
> Please refer the changes in YUNIKORN-1351 for more details.
