 Description   

Basically I would like to see a feature that would allow a map reduce job to run across multiple source collections, each with its own map function, and then have the values emitted be processed by a single reduce function. This could be used to support very simple join scenarios where the reduce function manually joins the different pieces of data that have been emitted for a given key.

I think SERVER-647 would work for this and other cases.
