title: Hadoop hdfs showing ls: `/home/hduser/input/': No such file or directory error
body: <p>I have installed <strong>Hadoop 2.6</strong> on single machine using <a href="http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html" rel="nofollow noreferrer">this tutorial</a>. I am using Ubuntu 12.04 machine and Java version 1.6.0_27.</p>
  <p>I have created separate user as <strong>hduser</strong> for Hadoop operations.
  I have set <strong>HADOOP_HOME</strong> envrioment variable's value <strong>/usr/local/hadoop</strong> where I have extracted the Hadoop distribution.</p>
  <p>Now I am following an <a href="http://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/MapReduceTutorial.html" rel="nofollow noreferrer"><strong>example</strong></a>. But when I execute the command <code>$HADOOP_HOME/bin/hdfs dfs -ls /home/hduser/input/</code> it gives following error -</p>
  <blockquote>
  <p>15/01/02 18:32:38 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
  ls: `/home/hduser/input/': No such file or directory</p>
  </blockquote>
  <p>Also I have tried command:
  <code>$HADOOP_HOME/bin/hdfs dfs -mkdir /home/hduser/input/</code>, but still getting same error.</p>
  <p>When I run the command <code>jps</code> it shows -</p>
  <pre><code>16023 SecondaryNameNode
  16200 ResourceManager
  16432 NodeManager
  18971 Jps
  15503 NameNode
  </code></pre>
  <p>It is not showing any process for <strong>JobTracker</strong> and  <strong>TaskTracker</strong>.</p>
  <p>How can I resolve this error and to start/list the process for <strong>JobTracker</strong> and  <strong>TaskTracker</strong>?</p>
