------------------------------------

             Summary: Add integration test for consumer coordinator
                 Key: KAFKA-2274
                 URL: https://issues.apache.org/jira/browse/KAFKA-2274
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Guozhang Wang
            Priority: Critical
             Fix For: 0.8.3


As discussed with Onur offline, here are some things we could test / simulate:

- consumer kill -9 (tested in ConsumerTest)
- broker kill -9 (tested in ConsumerTest)
- consumer very long GC
- broker very long GC
- consumer network cable unplugged
- broker network cable unplugged
- consumer power cord unplugged
- broker power cord unplugged

Quoting Onur: " Another motivating factor is to verify if response.wasDisconnected is good enough or if we actually need consumers to detect coordinator failures with timeouts.

GC’s can be simulated with SIGSTOP and SIGCONT. I think we might be able to simulate network cable being unplugged with "ifconfig eth0 down”, but I’m not sure."
