title: Kafka Consumer outputs excessive DEBUG statements to console (ecilpse)
body: <p>I'm running some sample code from <a href="http://www.javaworld.com/article/3060078/big-data/big-data-messaging-with-kafka-part-1.html?page=2" rel="noreferrer">http://www.javaworld.com/article/3060078/big-data/big-data-messaging-with-kafka-part-1.html?page=2</a>, and the kafkaconsumer is consuming from topic as desired, but every poll results in print (to std out) of many debug logs, which I don't want.</p>
  
  <p>I have tried changing all INFO and DEBUG to ERROR (even did a grep to make sure) in <code>/config/log4j.properties</code>, in particular setting <code>log4j.logger.kafka=ERROR</code>, kafkaAppender, but the problem persists. I referred to <a href="https://stackoverflow.com/questions/35773780/how-to-configure-logging-for-kafka-producers">How to configure logging for Kafka producers?</a>, and adopted the solution there, but perhaps the situation is different for consumers?</p>
  
  <p>The DEBUG messages all have a similar format:</p>
  
  <pre><code>[Thread-0] DEBUG org.apache.kafka.clients.consumer.internals.Fetcher - Sending fetch for partitions... to broker... (id: 0 rack: null)
  </code></pre>
  
  <p>and are appearing at rate of 10 every second or so (changing poll argument to 1000 or even 10000 doesn't help, I tried)</p>
  
  <p>Would really appreciate any help from any expert. Thanks in advance!</p>
  
  <p>Edit: Not sure if it matters, but I added <code>BasicConfigurator.configure();</code> to my main method, to resolve some other error occurring previously that stopped the Consumer from even starting.</p>
