title: what's the difference between "hadoop fs" shell commands and "hdfs dfs" shell commands?
body: <p>Are they supposed to be equal?</p>
  
  <p>but, why the "<code>hadoop fs</code>" commands show the <code>hdfs files</code> while the "<code>hdfs dfs</code>" commands show the local files?</p>
  
  <p>here is the hadoop version information:</p>
  
  <blockquote>
    <p>Hadoop 2.0.0-mr1-cdh4.2.1 Subversion
