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 method does not return trackers, it returns number of trackers.

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();

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

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

        Summary: getBlacklistedTrackers() should be deprecated and a new method called  getNumBlacklistedTrackers should be added.   (was: getBlacklistedTrackers() is misleading. It does not return trackers. It should be renamed getNumBlacklistedTrackers. )
