DNS look up for service Dns failed. Name not found.

[MrinalMSSharma]

Hi, I'm using Spring 3.2 and I'm trying to integrate hazelcast with kubernetes in EKS environment. Since I'm using XML configuration so unable to put YAML configurations. Is there any way if we can provide role based access through XML or Java code. I keep getting warnings for DNS look up failed, may be because I have not added any RBAC configuration.
Kindly help.

Zip file contains the XML.
