    Description

      Kafka brokers are unable to connect to zookeeper which is behind an ELB.

      Kafka is using zkClient which is caching the IP address of zookeeper and even when there is a change in the IP for zookeeper it is using the Old zookeeper IP.

      The server.properties has a DNS name. Ideally kafka should resolve the IP using the DNS in case of any failures connecting to the broker.
