Dpark is a Python clone of Spark, MapReduce computing 
framework supporting regression computation.

Word count example wc.py:

 from dpark import DparkContext
 ctx = DparkContext()
 file = ctx.textFile("/tmp/words.txt")
 words = file.flatMap(lambda x:x.split()).map(lambda x:(x,1))
 wc = words.reduceByKey(lambda x,y:x+y).collectAsMap()
 print wc

This scripts can run locally or on Mesos cluster without
any modification, just with different command arguments:

$ python wc.py
$ python wc.py -m process
$ python wc.py -m mesos

See examples/ for more examples.
