title: How incorporate Storm component-specific configuration data?
body: <p>I have a Storm topology containing spouts/bolts. 
  There is some configuration data that is specific to a particular spout and
  also a particular bolt that I would like to use (i.e. read from a config file)
  so that it is not hard coded. Examples of config data is a filename that the
  spout is to read from and a filename that a bolt is to write to.
  I think config data is passed into the open and prepare methods.</p>
  
  <p>How can I incorporate the component-specific data from a configuration file?</p>
