Aaron Kimball commented on HADOOP-6323:
---------------------------------------
@Tom this isn't a new check -- MapOutputBuffer.collect() already did this exact
same check. But for MapOutputBuffer to use a generic serialization API that
isn't necessarily class-based, this check is just being pushed down into the
SerializerBase.serialize() method.
@Doug - Sure, I'll have WritableSerialization throw. AvroSerialization can't
create the schema in the c'tor; the {{AvroSerialization.getSchema()}} method
takes in the metadata as well as an example instance being serialized. That is
not yet available when the AvroSerializer is being constructed. I don't see how
AvroReflectSerialization would work without this.
