Let's say you have one very large input file
) is the map key, and the map value is
the field contents. How is this incorrect? I think this follows your earlier
suggestion of:
You may want to play with the following idea: collect key = column_number and
value = column_contents in your map step.

I am sorry for the confusion. I meant distributed data.
So help me out here. For example, if I am reducing to a single file, then my
main transformation logic would be in my mapping step since I am reducing away
from the data?

computation areas or is the reduce the major computation area?
Thanks.

So to be distributed in a sense, you would want to do your computation on the
disconnected parts of data in the map phase I would guess?
