title: Install mahout in windows 7 under cygwin
body: <p>I have successfully installed hadoop under cygwin in Windows 7 pro 64 bit.</p>
  
  <p>Now I'm working on installing mahout and I can't. </p>
  
  <p>After setting the MAHOUT_HOME and variable and running mahout on cygwin I get the following error</p>
  
  <p>I guess it has to do with the compatibility issues between cygwin and windows paths but I can't find which specific path should I change.</p>
  
  <pre><code>Running on hadoop, using /cygdrive/c/hadoop/bin/hadoop and HADOOP_CONF_DIR=
