title: Apache Kafka: bootstrap-server is not a recognized option
body: <p>I'm trying to set up Apache Kafka to communicate between two virtual machines running CentOS on the same network. I originally set up a Kafka producer and consumer on one machine and everything was running smoothly. I then set up Kafka on the other machine and in the process of trying to get them to connect, I get the error "bootstrap-server is not a recognized option" (I'm running the most recent version of Kafka, 2.2).</p>
  
  <p>This is what I used to attempt a producer connection:</p>
  
  <p><code>bin/kafka-console-producer.sh --bootstrap-server 10.0.0.11:9092 --topic test</code></p>
  
  <p>And on the consumer side:</p>
  
  <p><code>bin/kafka-console-producer.sh --bootstrap-server 10.0.0.11:9092 --topic test</code></p>
  
  <p>The <code>10.0.0.11</code> machine is running the server itself.</p>
