> Right now, jon tracker keeps track the number of launched mappers with local data.
> However, it is not clear how many mappers that are potentially be launched with data locality.
> This information is readily available in Job Tracker. It is just a matter to create a separate global counter
> and set it at the Job Tracker initialization time.
