title: Is there ln in hadoop HDFS
body: <p>Is there <code>ln -s</code> in hadoop HDFS?</p>
  
  <p>For instance:</p>
  
  <p>I have 10 files in HDFS</p>
  
  <p><code>/user/hadoop/input</code>, which is <code>1.txt, 2.txt ... 10.txt</code></p>
  
  <p>Another dir in HDFS is <code>/user/hadoop/test</code></p>
  
  <p>I just wanna copy 1 file from  <code>/user/hadoop/input/1.txt</code> to  <code>/user/hadoop/test/1.txt</code>.</p>
  
  <p>The simplest way is use <code>hadoop dfs -cp /user/hadoop/1.txt /user/hadoop/test</code>.</p>
  
  <p>But it cost more time and disk space. Is there a way like shell such as <code>hadoop dfs -ln /user/hadoop/1.txt /user/hadoop/test/1.txt</code> ?</p>
