> The RCFile implementation was copied from Hadoop's SequenceFile and copied
> the 'magic' string in the header. This means that you can't use the header to
> distinguish between RCFiles and SequenceFiles.
> I'd propose that we create a new header for RCFiles (RCF?) to replace the
> current SEQ. To maintain compatibility, we'll need to continue to accept the
> current 'SEQ\06' and just make new files contain the new header.
