title: Consuming with Kafkacat shows no messages, although using -o beginning
body: <p>I'm trying to consume from a topic using Kafkacat , using the following command:</p>
  <pre><code>kafkacat -b *****:9093 -C -K\t -X security.protocol=SASL_SSL -X sasl.mechanisms=SCRAM-SHA-512 -X sasl.username=**** -X sasl.password=**** -t **** -o beginning
  </code></pre>
  <p>The response for the command is:</p>
  <pre><code>% Reached end of topic **** [0] at offset 121507
  % Reached end of topic **** [2] at offset 186701
  % Reached end of topic **** [1] at offset 175697
  </code></pre>
  <p>Now - Shouldn't the flag -o beginning show me all of the messages? I'm trying to understand how to begin at the first offset without success</p>
