title: Tried to install Hadoop - getting Permission denied errors
body: <p>I followed <a href="http://hadoop.apache.org/docs/r2.4.0/hadoop-project-dist/hadoop-common/SingleCluster.html#Fully-Distributed_Operation" rel="nofollow">this</a> Hadoop tutorial here.</p>
  
  <p><em>My end goal is to install Hadoop and Spark, and what not on my Mac</em>, but honestly, I'm an amateur at this thing, at best.</p>
  
  <p>So, I got up to step 2, under Execution of <strong>Psuedo-Distributed Operation</strong> and then the following appears:</p>
  
  <pre><code>sudo start-dfs.sh

  </code></pre>
  
  <p>Basically, I typed in my password for user lanceguinto, and it is apparently incorrect. Of note is that I did not follow the <strong>Setup passphraseless ssh</strong> portion because I thought it was unnecessary - I can already ssh, but I'm entirely sure that code does.</p>
  
  <p>During the setup, I also simply used my local user. I did not sudo su / anything.</p>
  
  <p>So, how can I solve this problem? Thanks.</p>
