Subject Map reduce technique
Date Wed, 06 Mar 2013 05:37:13 GMT

I am new to map reduce paradigm. I read in a tutorial that says that 'map' function splits
the data and into key value pairs. This means, the map-reduce framework automatically splits
the data into pieces or do we need to explicitly provide the method to split the data into
pieces. If it does automatically, how it splits an image file (size etc)? I see, processing
of an image file as a whole will give different results than processing them in chunks.

With thanks and regards
