title: Hadoop "cd" (change directory command) doesn't work
body: <p>I am learning Hadoop. What an interesting world. Hats off to Tom White and all folks contributing to Apache Hadoop.</p>
  
  <p>I was practicing hadoop commands like rmdir</p>
  
  <p>$hadoop fs -rmdir hadoop-test1</p>
  
  <p>It says directory not empty. 
  So next obvious step would be to go to "hadoop-test1" directory and delete the contents in that directory. </p>
  
  <p>So I tried to use linux "cd" command to go to "hadoop-test1" directory</p>
  
  <p>It says there is not "cd" command. </p>
  
  <p>Any reason why "cd" is not in hadoop?</p>
  
  <p>thanks</p>
