Mrs (pronounced "missus") is a lightweight implementation of MapReduce. The name derives from the practice of referring to MapReduce programs by the title "mister" (e.g., "Mr. Wordcount"). The name "Mrs" is a natural variation on "Mr" and more memorable than an arbitrary acronym.
Mrs is a MapReduce implementation that aims to be easy to use and reasonably efficient. It is written in Python and where possible builds on existing solutions to remain lightweight. Python 2 (>=2.6) and Python 3 are supported. Mrs is licensed under the GNU GPL.
The MapReduce paper <http://research.google.com/archive/mapreduce.html> provides
an introduction to MapReduce. The examples/wordcount.py <http://code.google.com/p/mrs-mapreduce/source/browse /examples/wordcount.py> file shows the Mrs WordCount based on the
corresponding program described in the paper.
