title: Cassandra - ERROR: Doesn't have write permissions for ./../data/data directory
body: <p>I just now installed Datastax Enterprise. I trying to run the commands. I am using OS X (Sierra).</p>
  
  <pre><code>cd dse/bin
  ./cassandra
  </code></pre>
  
  <p>After some process I am getting errors like this:</p>
  
  <pre><code>ERROR 02:29:11 Doesn't have write permissions for ./../data/data directory
  ERROR 02:29:11 Insufficient permissions on directory ./../data/data
  </code></pre>
  
  <p>I saw one of the similar <a href="https://stackoverflow.com/questions/33047141/how-to-configure-access-permissions-for-cassandra-on-linux-ubuntu/33048712">issue</a> and found thier suggestion that run below commands:</p>
  
  <pre><code>sudo chown -R cassandra:cassandra /var/lib/cassandra/data
  sudo chown -R cassandra:cassandra /var/lib/cassandra/commitlog
  </code></pre>
  
  <p>Even now I am getting other issue:</p>
  
  <pre><code>chown: cassandra: illegal group name
  </code></pre>
