> Having defined a recorddelimiter of multiple bytes in a new InputFileFormat
> sometimes has the effect of skipping records from the input.
> This happens when the input splits are split off just after a
> recordseparator. Starting point for the next split would be non zero and
> skipFirstLine would be true. A seek into the file is done to start - 1 and
> the text until the first recorddelimiter is ignored (due to the presumption
> that this record is already handled by the previous maptask). Since the re
> ord delimiter is multibyte the seek only got the last byte of the delimiter
> into scope and its not recognized as a full delimiter. So the text is skipped
> until the next delimiter (ignoring a full record!!)
