David Carr updated AVRO-1394:
-----------------------------
Attachment: AVRO-1394.patch
Patch attached with proposed enhanced error. Please review according to the
code review checklist. No test is included, as wording of error symbols
doesn't seem to be something that is currently tested. If that is not the
case, I'd be happy to provide a test.
I grant license to the ASF to include this patch in ASF works as per the Apache
license.

> 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.
