title: How to disable zookeeper debug messages in Spring application?
body: <p>Thanks in advance.</p>
  
  <p>My application uses <code>Spring 4.0.1.RELEASE</code> version. It uses the <code>maven</code> dependencies for this application. 
  The application is also using <code>Apache Kafka</code> JAVA API to connect to <code>Kafka Broker</code> to send and receive messages.
  The application is web based application where we also have the <code>REST</code> web services to consume the message from other applications.</p>
  
  <p>PROBLEMS FACING CURRENTLY <br>
  1. <code>Kafka</code> uses the <code>zookeeper</code> client and it is continuously receiving the ping messages from zookeeper.<br>
  <b><br>
  DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: after 242ms.</b><br><br>
  I want to disable this message as well as stop ping response from client to <code>zookeeper</code> server. It does not allow to start the <code>Tomcat</code> server completely.
  <br><br>
  2. Also how I can disable the DEBUG messages for <code>Spring</code> and other applications.</p>
  
  <p>I tried all other methods but does not got any success.</p>
  
  <p>Thanks again in advance.</p>
