> So I ran into this a long time ago and only just now remembered to document it:
> kafka-console-consumer.sh takes a --property option, but this option is just an argument for the message formatter. I've had ~10 users ask why --property wasn't properly applying their consumer configuration key-value pairs. The tool doesn't provide a description for --property, either. I know in the past, the user was able to provide all consumer configurations from the command line instead of from a file, so it's pretty understandable why the mistake would be made.
> Some solutions are:
> 1. just add a description to --property to the existing tool. It's not ideal because the "property" name is still there, but it seems unlikely to break existing users.
> 2. fix the existing kafka-console-consumer option name. This breaks existing users so probably not okay.
> 3. make KAFKA-2015 actually a brand new console consumer with a more accurate option name like --formatter-arg or --formatter-args. This won't break existing users.
