KAFKA-2274: verifiable consumer and integration testing
----
> Add integration test for consumer coordinator
> ---------------------------------------------
>
> Key: KAFKA-2274
> URL: https://issues.apache.org/jira/browse/KAFKA-2274
> Project: Kafka
> Issue Type: Sub-task
> Components: consumer
> Reporter: Guozhang Wang
> Assignee: Jason Gustafson
> Priority: Blocker
> Fix For: 0.9.0.0
>
>
> 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."
