Description

When running the producer performance test without providing a messages argument, you get an error:

$bin/kafka-producer-perf-test.sh --topics mirrormirror --broker-list kafka-dc21:9092
Missing required argument "[messages]"

Option                                  Description
------                                  -----------
......
--messages <Long: count>                The number of messages to send or
                                          consume (default:
                                          9223372036854775807)

However the shell command documentation doesn't say that this is required and implies that 2^63-1 (Long.MaxValue) messages will be sent. It should probably look like the ConsoleProducer and prefix the documentation with REQUIRED. Or should we make this a non-required argument and set the default value to something sane like 100,000 messages.

Which option is preferable for this?
