Is your data in any given file a bunch of key-value pairs? If that isn't the case, I'm wondering how writing a single large key-value into a sequence file helps. It won't. May be you can give an example of your input data?
If indeed they are a bunch of smaller sized key-value pairs, you can write your own custom InputFormat that reads the data from your input files one k-v pair after another, and feed it to your MR job. There isn't any need for converting them to sequence-files at that point.
