title: Using Parameters in python luigi
body: <p>I have am triggering Luigi via</p>
  
  <pre><code>luigi.run(["--local-scheduler"], main_task_cls=Test(Server = ActiveServer, Database = DB))   
  </code></pre>
  
  <p>and in my class I have:</p>
  
  <pre><code>class Test(luigi.Task):
  
      Database = luigi.Parameter()
      Server = luigi.Parameter()
  </code></pre>
  
  <p>but the task test can't seem to parse the parameters that I'm feeding it properly?</p>
  
  <p>I am getting:</p>
  
  <pre><code>MissingParameterException: No value for 'Server' (--Server) submitted and no default value has been assigned.
  </code></pre>
