title: Publish message to kafka via http
body: <p>I'm new with kafka and I'm trying to publish data from external application via http but I cannot find the way to do this. </p>
  
  <p>I already created a topic in kafka and test it producing and consuming the message but I don't know how to insert/publish message via http, I tried to invoke the following url to retrieve the topics but it does not retrieve any data <a href="http://servername:2181/topics/" rel="nofollow noreferrer">http://servername:2181/topics/</a> </p>
  
  <p>I'm using cloudera 5.12.1.</p>
