Stu Hood commented on AVRO-603:
-------------------------------
> That doesn't work well if the reader's schema is a union.
Sorry, 'generic object' is overloaded here... I meant the K in
SpecificDatumReade<K>.
> SpecificDatumReader requires the reader's schema to be set manually

> Key: AVRO-603
> URL: https://issues.apache.org/jira/browse/AVRO-603
> Project: Avro
> Issue Type: Improvement
> Components: java
> Reporter: Stu Hood
> Priority: Minor
>
> 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.
