Jeff Hammerbacher commented on AVRO-1502:
-----------------------------------------
Spark relies on Java's Serializable interface to serialize objects. Avro
objects don't implement Serializable. So, to work with Avro objects in Spark,
you need to subclass your Avro generated classes and implement Serializable,
e.g.

> Avro objects should implement Serializable
