             Summary: Better error information when new record field has no default
                 Key: AVRO-1394
                 URL: https://issues.apache.org/jira/browse/AVRO-1394
             Project: Avro
          Issue Type: Improvement
            Reporter: David Carr
            Priority: Minor


Currently, if you add a field to a schema without a default, and attempt to read a record with the new schema that was written with the old (pre-field-creation) schema, you get an error like this:

org.apache.avro.AvroTypeException: Found mypackage.MyRecordType, expecting mypackage.MyRecordType

This message is accurate, but doesn't help the user recognize the real problem: there's a required field that isn't present in the written data.  Please enhance the error message to make it more informative.
