The Using AMQ Streams on RHEL guide uses the zookeeper option in multiple commands; see, for example, "Modifying a topic configuration". This option is deprecated in ZooKeeper and should be replaced by the bootstrap-server (plus port) option.

It is not a simple find and replace because the old option might still be required in some of the Kafka command line tools. Each command must be verified as working when the new command is passed in.

See KIP-377 for background information.
