title: Getting acks = -1 when I set acks to all in my Kafka producer
body: <p>I set the following property on my Kafka producer:</p>
  <pre class="lang-java prettyprint-override"><code>properties.setProperty(ProducerConfig.ACKS_CONFIG, &quot;all&quot;);
  </code></pre>
  <p>When I start my application I see <code>acks = -1</code> in the <code>ProducerConfig values</code>. Why is this?</p>
