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.

To run DPark on Mesos (0.9 or latest), need MESOS_MASTER and DPARK_WORK_DIR, such as:

$ export MESOS_MASTER = zk://zk1:2181,zk2:2181,zk3:2181,zk4:2181,zk5:2181/mesos_master 
$ export DPARK_WORK_DIR = /data1/dpark

In order to speed up shuffing, should deploy Nginx at port 5055 for accessing data in DPARK_WORK_DIR, such as:

        server {
                listen 5055;
                server_name localhost;
                root /data1/dpark/;
        }
