Reduce: com.google.appengine.tools.mapreduce.Reducer; com.google.appengine.tools.mapreduce.ReducerInput;
== Program Profile ==
Nothing about parallelism here. This is an interface that communicates different parts of program and join them together. There are 3 sections here: mapping pattern, reduce pattern and file port (where the data came from). Platform Library will be pre-loaded in ever instance and no need to call. Default user interface calling section is included in every project.
