Question:
When a pod run plugins failed in scheduing cycle, for example, run reserve plugins, it will execute handleSchedulingFailure funtion, the code is: kubernetes/pkg/scheduler/schedule_one.go at master · kubernetes/kubernetes · GitHub.
And handleSchedulingFailure funtion will store the pod into a map which is nominatedPodToNode, the code is: kubernetes/pkg/scheduler/internal/queue/scheduling_queue.go at master · kubernetes/kubernetes · GitHub and kubernetes/pkg/scheduler/internal/queue/scheduling_queue.go at master · kubernetes/kubernetes · GitHub.
But when call addNominatedPodUnlocked funtion, the nominatingInfo argument may be this value: kubernetes/pkg/scheduler/schedule_one.go at master · kubernetes/kubernetes · GitHub
so it will store a key with empty string in nominated map: kubernetes/pkg/scheduler/internal/queue/scheduling_queue.go at master · kubernetes/kubernetes · GitHub
