title: Opening a port on HDInsight cluster on Azure
body: <p>I have a microsoft Azure HDInsight cluster. </p>
  
  <p>On the node I am rdp'ing and starting an application that binds to port 8080. I would like to be able to connect to this application from outside the cluster.</p>
  
  <p>I have my cluster connection string (<a href="https://xxxxx.azurehdinsight.net" rel="noreferrer">https://xxxxx.azurehdinsight.net</a>)  however when I try to connect to it I am timing out.</p>
  
  <p>I believe this is due to the fact that I have not opened port 8080 to public. How can I do this as under the cluster I only have Hadoop Services and username....</p>
