title: Why is it keep showing deprecated error when running hadoop (or dfs command)
body: <p>I've installed <em>hadoop-2.0.0-alpha</em>, but whenever I execute a command, it gives me deprecation errors (although it seems like to be running without problem)</p>
  
  <pre><code>$ hadoop/bin/hadoop dfs -copyFromLocal input input
  DEPRECATED: Use of this script to execute hdfs command is deprecated.
  Instead use the hdfs command for it.
  
  $ hadoop/bin/hadoop dfs -rmr input
  DEPRECATED: Use of this script to execute hdfs command is deprecated.
  Instead use the hdfs command for it.
  
  rmr: DEPRECATED: Please use 'rm -r' instead.
  </code></pre>
  
  <p>I googled around and it looks like it's a bug for <em>hadoop-0.23</em>. However, my version is more recent.</p>
  
  <p>I couldn't find an answer for this version, is it still an existing bug?</p>
