title: Kafka Console Producer returns nothing
body: <p>Hi I'm going through the <a href="https://kafka.apache.org/quickstart" rel="nofollow noreferrer">quick start</a> and I'm running into an error where when I type in <code>bin/kafka-console-producer.sh --broker-list localhost:9093 --topic first</code></p>
  
  <p>I get nothing back when I'm expecting a text input to send the message to the Kafka producer. I have followed the instructions for a single and multi-broker set up but it doesn't seem like anything is working. My Zookeeper is running and I see the log files created in the correct log directories but nothing regarding my message.</p>
  
  <p>I have also tried piping it like so <code>cat test.txt | bin/kafka-console-producer.sh --broker-list localhost:9093 --topic first</code> or <code>echo test message | bin/kafka-console-producer.sh --broker-list localhost:9093 --topic first</code> </p>
  
  <p>Is there any other gotchas I should check out for?</p>
