About MapReduce and HDFs
What is Hadoop?
Google has proposed programming model MapReduce and Distributed file system for its business needs, and published relevant papers (available on Google Research's website: GFS, MapReduce). Doug Cutting and Mike Cafarella made their own implementations of the two papers when they developed the search engine Nutch, namely, MapReduce and HDFs, which together are Hadoop.
The data flow of mapreduce, for example, was processed by mapper, then partition and sort
