------------------------------------
Thanks for the explanation [~ewencp]. That sounds good. It would be good to
update

with the instructions once ready.
> ConsoleConsumer regressions
> ---------------------------
>
> Key: KAFKA-2467
> URL: https://issues.apache.org/jira/browse/KAFKA-2467
> Project: Kafka
> Issue Type: Bug
> Components: tools
> Reporter: Ewen Cheslack-Postava
> Assignee: Ewen Cheslack-Postava

> It seems that the patch for KAFKA-2015 caused a few changes in the behavior
> of the console consumer. I picked this up because it caused the new mirror
> maker sanity system test to hang. We need a separate fix for ducktape to
> address the lack of a timeout where it got stuck, but I'd also like to get
> this fixed ASAP since it affects pretty much all system test efforts since
> they commonly use console consumer to validate data produced to Kafka.
> I've tracked down a couple of changes so far:
> 1. The --consumer.config option handling was changed entirely. I think the
> new approach was trying to parse it as key=value parameters, but it's
> supposed to be a properties file *containing* key=value pairs.
> 2. A few different exceptions during message processing are not handled the
> same way. The skipMessageOnErrorOpt is not longer being used at all (it's
> parsed, but that option is never checked anymore). Also, exceptions during
> iteration are not caught. After fixing the consumer.config issue, which was
> keeping the consumer.timeout.ms setting from making it into the consumer
> config, this also caused the process to hang. It killed the main thread, but
> there must be another non-daemon thread still running (presumably the
> consumer threads?)
> 3. The "consumed X messages" message changed from stderr to stdout.
