> -----------------------------------------------------------------------
>
> Key: KAFKA-6971
> URL: https://issues.apache.org/jira/browse/KAFKA-6971
> Project: Kafka
> Issue Type: Improvement
> Components: core, producer
> Affects Versions: 1.1.0
> Reporter: Yeva Byzek
> Priority: Minor
> Labels: newbie
>
> {{kafka-console-consumer --help}} prints "help is not a recognized option" as
> well as output of options
> {{kafka-console-producer --help}} prints "help is not a recognized option"
> but no output of options
> Possible solutions:
> (a) Enhance {{kafka-console-producer}} to also print out all options when a
> user passes in an unrecognized option
> (b) Enhance both {{kafka-console-producer}} and {{kafka-console-consumer}} to
> legitimately accept the {{--help}} flag
