With the current version of the ConsoleConsumer, ConsumerPerformance and ConsumerGroupCommand command line tools, it's not needed to specify the --new-consumer option anymore in order to use the new consumer. The choice for using the old or the new one is made just specifying the --zookeeper for the farmer former and --bootstrap-server for the latter.

...

The first step should be the deprecation of the --new-consumer option in the next release. The following JIRAs KAFKA-5599 and KAFKA-5619 and is already opened for addressing that. The command line tools will set the option as deprecated and print a warning messages in case the user uses it.On the next release cycle we could totally remove the option

This option will be removed in the 2.0.0 release.
