mapReduce vs erlang

[Only OpenSource]

Hello

I was reading about mapReduce at
http://en.wikipedia.org/wiki/MapReduce

and it seemed to have many capabilities similar to erlang.
In addition since it is implemented in C++, the data processing capabilities
seem to be quite impressive.

Now that Nutch project has an implementation of mapReduce,
what areas Erlang would be able to make a difference ?
