title: How to run hadoop balancer from client node?
body: <p>I want to ask how can I run the hadoop balancer? I've tried before on the namenode to run hadoop balancer command, but it has no effect at all (my new datanode still empty). I also read that hadoop balancer is not run on namenode but on client node. So what is the client node, how can I configure it, and how can client node access the hadoop file system?</p>
  
  <p>Thanks all, I need your suggest</p>
