How to pass arguments to mapper/reducer?

[gglanzani]

I'm trying to pass some arguments to a mapper.

With the Riak client I trivially do it with the snippet erlang-shell in this gist

The problem is how to achieve the same with Python. In the same gist as above, I have the snippets python-{first,second}-try and python-first-fail which is the traceback.

In the gist I've also included the Erlang code (sorry if it's ugly, it's my first Erlang week).

Am I doing something wrong? I couldn't find much in the documentation.

@gglanzani It looks like you are passing in the options dict with a key of args instead of arg. See if that works any better for you. I think we should make the values to options a bit clearer in the documentation.

@javajolt Yes, you are right, sorry for the inconvenience. As an aside: I still don't get the results because of #394 :)

Regarding the docs: I think the could use some love too. A working MR example would be appreciated by the audience.

Keep up the good work!

@lucperkins Your fans would love more M/R examples. Do we have something more detailed? Or are there plans to add other language examples to http://docs.basho.com/riak/latest/dev/using/mapreduce/?
