In my application I have a file in this format: The first line of the file contains the data to be processed, and *each* of the remaining lines contain parameters that will be used to slice & dice the data in various ways. In other words, each mapper needs two lines - the 1st line from this file that contains data and another line that contains parameters.
I looked at NLineInputFormat which can be used for "parameter sweeps", but it's not quite what I want. I believe this format returns N no. of consecutive lines to the mapper, correct? What's the best way to handle this case? Do I have to write a special InputFormat class? Please help. Thanks.
