> Since SpecificDatumReader has actual objects with schemas attached to them, it would
seem that you wouldn't need to set the reader's schema: the default constructor only takes
one schema argument, so it seems to support this, but behind the scenes, it sets the readers/writers
to the same schema.
> Additionally, since DatumReader and its implementations use the terms 'expected' and
'actual' to refer to the 'reader' and 'writer' schemas, determining that you need to set the
reader's schema requires a code dive, rather than a glance at the javadocs.
