title: Hadoop:/usr/lib/hadoop-0.20.2/conf/slaves: No such file or directory
body: <p>I followed the steps on the hadoop offical site exactly as it says, but it always shows the following error:</p>
  
  <pre><code>starting namenode, logging to /home/videni/Tools/hadoop-1.0.3/libexec/../logs/hadoop-videni-namenode-videni-Latitude-E6400.out
  cat: /usr/lib/hadoop-0.20.2/conf/slaves: No such file or directory
  cat: /usr/lib/hadoop-0.20.2/conf/masters: No such file or directory
  starting jobtracker, logging to /home/videni/Tools/hadoop-1.0.3/libexec/../logs/hadoop-videni-jobtracker-videni-Latitude-E6400.out
  cat: /usr/lib/hadoop-0.20.2/conf/slaves: No such file or directory
  </code></pre>
  
  <p>Right now, i just want to set a Standalone Operation, should I have to set the three xml files, such as core-site.xml, hdfs-site.xml, mapred-site.xml?<br>
  I checked the log files, some of them say <code>Error: JAVA_HOME is not set</code>, but I set it in the hadoop-env.sh file.</p>
