title: Hadoop Name node not listed while using jps command
body: <p>I am new to hadoop. I installed hadoop by following link.
  <a href="http://www.bogotobogo.com/Hadoop/BigData_hadoop_Install_on_ubuntu_single_node_cluster.php" rel="nofollow">http://www.bogotobogo.com/Hadoop/BigData_hadoop_Install_on_ubuntu_single_node_cluster.php</a> </p>
  
  <p>All installation was done.After that executed <code>start-all.sh</code> command.</p>
  
  <p>Server started sucessfully. But when typing <code>jps</code> command it's not listing name node.Output as shown below.</p>
  
  <pre><code>6917 SecondaryNameNode
  7185 NodeManager
  6746 DataNode
  7060 ResourceManager
  7476 Jps
  </code></pre>
  
  <p>In hadoop-hduser-namenode-nag-VirtualBox.log log file shows fallowing output.</p>
