-------------------------------------
Also, I opened AVRO-603 to handle clarifying these docs.
> Avro Schema Swap

> Project: Cassandra
> Issue Type: Bug

> Priority: Critical

> Due to misreading Avro's docs, I swapped the Schema parameters to Avro's
> schema resolver.
> The schema resolver allows for backwards compatibility by accepting a
> writer's (ser.) and reader's (deser.) schema, and resolving them to determine
> which fields to add or ignore. The reader's schema was not being set
> correctly, which was breaking backwards compatibility (although not the disk
> format).
