> Add an OutputFormat to write raw bytes as keys and values to a SequenceFile.
> In C++-Pipes, we're using SequenceFileAsBinaryInputFormat to read Sequencefiles.
> However, we current don't have a way to *write* a sequencefile efficiently without going
through extra (de)serializations.
> I'd like to store the correct classnames for key/values but use BytesWritable to write
> (in order for the next java or pig code to be able to read this sequencefile).
