Without all the information, I'm gussing that "java.lang.Cl" is a
ClassCastException. That would happen if your read schema doesn't have
the necessary java-class properties that cause Avro to instantiate your
specific object rather than a GenericData.Record object.
I recommend taking the schema you are using for the read schema and
building a Specific object for it. Then you can use that stripped-down
specific object as you were before (call it PartialProfile or something)
to avoid this issue.
Actually, I think it might need the same name (and namespace) as the
original object. You will want to build this job with the read schema
and object generated by it replacing the original object.
