I have 3 brokers running with broker id s 0 1 and 2. The Consumer (Java Client) picks up broker 0 as group coordinator and starts to consume messages correctly. But when the broker 0 which is the group coordinator is down, the consumer does not do anything and stalls on the poll() method. The process resumes only when that broker 0 is up and running.

How to handle this scenario of group co-ordinator change in the Java client?

I get this error when group coordinator dies:
