HADOOP-3063 BloomMapFile - fail-fast version of MapFile for sparsely
populated key space (Andrzej Bialecki via stack)
HADOOP-1230. Add new map/reduce API and deprecate the old one. Generally,
the old code should work without problem. The new api is in
org.apache.hadoop.mapreduce and the old classes in org.apache.hadoop.mapred
are deprecated. Differences in the new API:
1. All of the methods take Context objects that allow us to add new
methods without breaking compatability.
2. Mapper and Reducer now have a "run" method that is called once and
contains the control loop for the task, which lets applications
replace it.
3. Mapper and Reducer by default are Identity Mapper and Reducer.
4. The FileOutputFormats use part-r-00000 for the output of reduce 0 and
part-m-00000 for the output of map 0.
5. The reduce grouping comparator now uses the raw compare instead of
object compare.
6. The number of maps in FileInputFormat is controlled by min and max
split size rather than min size and the desired number of maps.
