nodegroup plugins don't use

[ffz12]

What happened:

When using the nodegroup plugin, the plugin is not recognized after it is added to the configmap of the volcano-scheduler-configmap. Check the volcano-scheduler-pod and the error E0418 07:21:42.912033 1 framework.go:40] Failed to get plugin nodegroup.

What you expected to happen:

The nodegroup plug-in can be used normally.

How to reproduce it (as minimally and precisely as possible):

1、Installed volcano
kubectl apply -f https://raw.githubusercontent.com/volcano-sh/volcano/master/installer/volcano-development.yaml

2、Modify the volcanic-scheduler-configmap configuration file as follows:
kind: ConfigMap
apiVersion: v1
metadata:
name: volcano-scheduler-configmap
namespace: volcano-system
data:
volcano-scheduler.conf: |
actions: "enqueue, allocate, backfill, reclaim, preempt"
tiers:
- plugins:
- name: priority
- name: gang
enablePreemptable: false
- name: conformance
- plugins:
- name: overcommit
- name: drf
enablePreemptable: false
- name: predicates
- name: proportion
- name: nodeorder
- name: nodegroup
- name: binpack

3、Change the log printing level of Volcanic-Scheduler to 2

4、The volcanic-Scheduler related pod is restarted

kubectl get po -n volcano-system | grep sche|awk '{print $1}'|xargs kubectl delete po -n volcano-system

5、View the logs of Volcanic-Scheduler

kubectl get po -n volcano-system | grep sche|awk '{print $1}'|xargs kubectl logs -n volcano-system
