title: hadoop: configuration files
body: <p>I am new to Hadoop. I am trying to setup a single-node cluster. </p>
  
  <p>I have noticed that in the documentation i've read (even on Apache's config site) it always refers to the configuration files in conf/ directory. However, when i download version 2.X.X i only see config files in the etc/hadoop directory. </p>
  
  <p>I have googled the heck out of this. i tried reading the hadoop documentation, but it refers to the 'conf' directory, as explained before. </p>
  
  <p>So, my question is: Do i just configure the files where they are, in the etc/hadoop directory, or do i need to move them to the conf directory (create it myself?). </p>
  
  <p>thanks</p>
