      Chukwa has many configuration options, and it's easy to mis-set them. I'd like to contribute a module for doing stronger static checks of configuration at startup.

      In particular, this will flag and log cases where:
      An option is set in the Chukwa config files that is never read by Chukwa.
      A non-numeric value is used for a numeric parameter, non-boolean value for boolean parameter, etc.

      The table of options and types is automatically generated and then human-checked. It should be easy to keep it up to date.
      The changes to the Chukwa codebase should be quite modest: one new Jar, and a handful of lines to invoke that Jar on startup.

      Does this sound like a thing people would like to see?
