I put all user global variables in a class I called MyGlobals.

Since map/reduce is distributed in general, you should be careful of  
using global variables. I find it to be better practice to keep all  
of the state variables in either the Mapper or Reducer itself to  
remind myself that it is _not_ shared between Mappers, Reducers, and  
the launching program.
