@Mahesh babu did you figure out this issue? I am seeing the same error in the AWS EKS kafka/pinot cluster I just deployed. I verified that I can ping zookeeper from the pinot-controller container. ShowClusterInfo crashes too and nothing useful on the internet so I'm at a dead-end on how to debug this
