Description

     In our K8S environment, there are multiple schedulers working simultaneously (provided by different vendors), and Yunikorn is currently unable to handle situations where pods in a certain namespace may need to be scheduled by different schedulers. The current approach is to intercept all pods in the namespace (enableYunikorn=true) and modify their schedularName. Regardless of whether its schedulerName value is default scheduler or other.

    We hope that Yunikorn can add process and bypassing of spec.schedulerName on pods in the configuration, just like namespace.

// case
admissionController.filtering.processSchedulerNames: ^default-scheduler$|^yunikorn$
admissionController.filtering.bypassSchedulerNames: ^other-scheduler$
