title: Cassandra: Command Not Found
body: <p>I am currently working on the Cassandra tutorials about data modeling. I cannot understand why whenever I try to run the cassandra service from the bin folder I receive the error:</p>
  
  <blockquote>
    <p>"Cassandra: command not found". </p>
  </blockquote>
  
  <p>The same happens if I try to run nodetool, or cqlsh utilities. Can anybody help me to resolve the problem?</p>
