the GetNodeInfo in file /pkg/scheduler/plugins/util/util.go and pkg/scheduler/plugins/nodeorder/noderorder.go shoud change node not found errors to kubernetes's node not found error,like this
errors.NewNotFound(v1.Resource("node"), name)

this function is called by k8s code (InterPodAffinityMatches function )when check pod Affinity.
in k8s function getMatchingAntiAffinityTopologyPairsOfPods,it will ignore node that not exist.

if err != nil {
			if apierrors.IsNotFound(err) {
				klog.Errorf("Node not found, %v", existingPod.Spec.NodeName)
				continue
			}
			return nil, err
		}
