title: Configuration of workers in a storm cluster
body: <p>I have a question about configuration of worker processes.</p>
  
  <p>I have already understood that worker processes run within a worker node (which is a machine). What I would like to know is if all worker processes share the same JVM  or if each worker process has its own JVM instance? If the latter is true, so I suppose one should set how much memory each process has to use! So where would this configuration be done?</p>
