title: Issues when using hadoop to copy files from grid to local
body: <p>I am trying to copy some files from the hadoop HDFS to local. I used the following command</p>
  
  <pre><code>hadoop fs -copyToLocal &lt;hdfs path&gt; &lt;local path&gt;
  </code></pre>
  
  <p>The size of the file is just 80M. I had run a job before where I had no issue in copying files of size 70MB to local. However, this time I am having Input/Output error</p>
  
  <pre><code>copyToLocal: Input/output error
  </code></pre>
  
  <p>can anyone tell me what could have gone wrong?</p>
