csi isilon driver on tanzu fails with no such host in isilon-node pod

Hi

We are trying to test isilon csi on TKC (vSphere with Tanzu 7U2). The isilon-node pods are failing with error "lookup x.x.x.x.in-addr.arpa ... x.x.x.x:53 no such host".

CSI version: 1.5.0 & 1.4.0.

K8S Node OS: Photon 3.0.

Not sure why it is looking up for that when it already found ip, we don't have any dns configured k8s nodes, is there any workaround to fix this?

Thanks,
