title: Kafka, timeout waiting for a node assignment?
body: <p>Following the getting started guide, I get the following error:</p>
  <blockquote>
  <p>org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment.
  (kafka.admin.TopicCommand$)</p>
  </blockquote>
  <p>What I have done is start the two servers with the commands:</p>
  <pre><code>bin/zookeeper-server-start.sh config/zookeeper.properties
  </code></pre>
  <p>and</p>
  <pre><code>bin/kafka-server-start.sh config/server.properties
  </code></pre>
  <p>and then execute the following command, where I'm getting the error:</p>
  <pre><code>bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic test
  </code></pre>
  <p>I'm running on macOS Mojave</p>
  <p>When starting the Kafka server, I obtain this log:</p>
