title: "Connection refused" Error for Namenode-HDFS (Hadoop Issue)
body: <p>All my nodes are up and running when we see using <code>jps</code> command, but still I am unable to connect to hdfs filesystem. Whenever I click on <code>Browse the filesystem</code> on the Hadoop Namenode localhost:8020 page, the error which i get is <code>Connection Refused</code>. Also I have tried formatting and restarting the namenode but still the error persist. Can anyone please help me solving this issue.</p>
