title: Excessive console messages from Kafka Producer
body: <p>How do you control the console logging level of a Kafka Producer or Consumer?  I am using the Kafka 0.9 API in Scala.</p>
  
  <p>Every time <code>send</code> on the <code>KafkaProducer</code> is called, the console gives output like below.  Could this indicate I do not have the <code>KafkaProducer</code> set up correctly, rather than just an issue of excessive logging?</p>
  
  <pre><code>17:52:21.236 [pool-10-thread-7] INFO  o.a.k.c.producer.ProducerConfig - ProducerConfig values: 
  compression.type = none
  metric.reporters = []
  metadata.max.age.ms = 300000

  </code></pre>
  
  <p>There are logging configurations in the <code>properties</code> files the Kafka server and Zookeeper look at, but I've assumed these do not affect Kafka clients.  Changing some of the logging configurations in these files, and restarting the Kafka server and Zookeeper so those files are reloaded, has not solved the problem.</p>
  
  <p>Thank you</p>
