> The functions countreducetasks and countmaptasks currently return the total number of
maps/reduces on the tasktracker. They should only return the number of running maps/reduces.
Because they return the total count, the jobtracker is not able to schedule tasks on these
tasktrackers in the current cycle, when a task is finished and the tasktracker is runnning
max number of maps/reduces.
