title: How to use Zookeeper with Azure HDInsight Linux cluster?
body: <p>Obviously I need to start a zookeeper server on one of the cluster machines, then I need other client machines to connect to this server.
  The way I did it is that I used ssh to connect to the headnode, I found a zk server running on the port 2181. So, I used ifconfig to get the machine's IP address (for example 10.0.0.8) and i then had my worker nodes connect to:
  10.0.0.8:2181.
  However, my MR job now completes but it works slowly and the output is not correct. I suspect that I'm doing something wrong with Zookeeper, especially that I didn't follow a tutorial and improvised my steps.</p>
