Pranay Varma updated MAPREDUCE-5347:
------------------------------------

    Description: 
If the method returns a number, then that is what the method name should reflect. It should be called getNumBlacklistedTrackers();

The same applies to the following:
- getMapTasks, getReduceTasks, getTaskTrackers

These should be deprecated and a new method should be added: getNumxxx. 

  was:If the method returns a number, then that is what the method name should reflect. It should be called getNumBlacklistedTrackers();
