>
> The CombineFileRecordReader operates on splits consisting of multiple files.
> Each time a new record reader is initialised for a "chunk", certain
> parameters are supposed to be set on the configuration object
> (map.input.file, map.input.start and map.input.length)
> However, the first reader is initialised in a different way to subsequent
> ones (i.e. initialize is called by the MapTask directly rather than from
> inside the record reader class). Because of this, these config parameters are
> not set properly and are returned as null when you access them from inside a
> mapper.
