Hi Kuldeep, Its look like Zookeeper pods are not in ready state(Probably pods keep restating due to infra issues.) by the time Kafka tried to connect to the Zookeeper. Addressing the Zookeeper issue will fix the issue.

Kafka pod (dev-dmaap-message-router-kafka-0 ) is failing due to the error with Kafka server startup (logs below), where auth is failing for ZooKeeperClient. Can someone help to get this addressed ?
