Pod cannot mount Persistent Volume created by ozone CSI provisioner - kubernetes

Question

I am using kubernetes to deploy ozone (a sub for hdfs), and basically followed instructions from here and here (just a few steps).
First I created few pvs with hostpath to my local dir, then I slightly edited the yamls from ozone/kubernetes/example/ozone by changing nfs claim to host path claim:
volumeClaimTemplates:
- metadata:
name: data
spec:
storageClassName: manual
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 5Gi
selector:
matchLabels:
type: local
and I commented out the nodeAffinity settings in datanode-stateful.yaml since my kubernetes only had master node.
The deployment was succesful.
Then I applied the csi and pv-test as the instructions in csi protocol said, the pv (bucket in s3v) was automatically established, and pvc did bound the pv, but the test pod stopped at containerCreating.
Attaching the pv-test pod desc:
