> We would like to have multiple different mappers that takes input from different locations
and output records with the same format. So the output of the mappers could be joint in the
reducer easily. We know this can be achieved in the current framework. But the way to achieve
it is not natural, less flexibility (need code change). Thus this would be a convenient feature
to have.
