Trouble setting up python mapreduce - mincemeat.py

Question

I am trying to setup mincemeat.py on my system and am installing from source into a prefix folder. I use virtualenv and have python installed from source into a prefix directory. I am trying to install mincemeat.py to the same prefix directory.

I downloaded mincemeat-0.1.2.tar.gz and unzipped it. It contains mincemeat.py, setup.py, and the build. I tried to install by using

python setup.py install -prefix="/nlu/users/ind/"

I also have example.py in the same folder mincemeat-0.1.2. I tried to start the client by giving

python mincemeat.py -p changeme localhost

but it cannot start the client. The error is:

error: uncaptured python exception, closing channel <__main__.Client at 0x1b9d5a8> 
(<class 'socket.error'>:[Errno 111] Connection refused 
 [/nlu/users/ind/lib/python2.7/asyncore.py|read|83] 
 [/nlu/users/ind/lib/python2.7/asyncore.py|handle_read_event|441] 
 [/nlu/users/ind/python2.7/asyncore.py|handle_connect_event|449])

How do I check if my mincemeat installation is right? Also, where should I place my example.py? Please suggest how to get this working.

Answer 1

You need to run BOTH server and client.

Commands to be executed in separated consoles:
Console 1 (first): python example.py
Console 2 (later): python mincemeat.py -p changeme localhost

Answer 2

mincemeat.py doesn't need to be set up or installed. If you have python 2.7 installed (which you do based on the error message) you should be able to run

python mincemeat.py -p changeme localhost

from the directory that has mincemeat.py in. I don't think the problem is how you installed mincemeat but some odd set up on your machine.

Do you only have IPV6 as in this post here: Python socket.error: [Errno 111] Connection refused on ubuntu 12.04 ?

Oh and you can put example.py in the same folder as mincemeat.py.
