> Currently to use the counters from within Map/Reduce code Enums have to be 
> used, the Enum class defines the group and the Enum itself the counter. 
> Internally they are converted to Strings (the class name and the enum 
> toString) and you can retrieve them as strings from the client API.
> Using dynamic counters (driven by configuration of the map/reduce) is not 
> easy with the counters Enum based API. For example, currently I have an Enum 
> class with 50 enums and we have to map the cardinality to the counter name on 
> the client. This is cumbersome.
> This could be easily improve by adding a String based counter method 
> increment(String group, String counter, long count) to allow use of the 
> counters without Enums.
> Internally this method already exists, so the changes are minimal.
