-------------------------------------
Summary: Add '--help' option to all available Kafka CLI commands
Key: KAFKA-7418
URL: https://issues.apache.org/jira/browse/KAFKA-7418
Project: Kafka
Issue Type: Improvement
Components: tools
Reporter: Attila Sasvari
Currently, the '--help' option is not recognized by some Kafka commands . For
example:
{code}
$ kafka-console-producer --help
help is not a recognized option
{code}
However, the '--help' option is supported by other commands:
{code}
$ kafka-verifiable-producer --help
usage: verifiable-producer [-h] --topic TOPIC --broker-list
HOST1:PORT1[,HOST2:PORT2[...]] [--max-messages MAX-MESSAGES] [--throughput
THROUGHPUT] [--acks ACKS]
[--producer.config CONFIG_FILE]
[--message-create-time CREATETIME] [--value-prefix VALUE-PREFIX]
...
{code}
To provide a consistent user experience, it would be nice to add a '--help'
option to all Kafka commands.
