title: Unable to start the zookeeper server
body: <p>I am running kafka on amazon EC2 and ubuntu. For starters I'm trying to run the zookeeper server and create a test topic. The ultimate aim is to integrate spark with kafka for sentiment analysis.</p>
  
  <p>When I try to start the zookeeper server I get the following warning and the process doesn't seem to end i.e I don't see a shell prompt after i type this command: 
  bin/zookeeper-server-start.sh config/zookeeper.properties</p>
  
  <p>WARN Either no config or no quorum defined in config, running  in standalone mode (org.apache.zookeeper.server.quorum.QuorumPeerMain)</p>
  
  <p>Thanks in advance for any help on this. </p>
