> 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."
