> Very similar to AVRO-1500.
> When in thrift schema (e.g. {{Test}}) with optional byte field:
> {code}
> 16: optional byte byteOptionalField
> {code}
> And it is initialized like:
> {code}
> test.setByteOptionalField((byte)4);
> {code}
> Then during conversion of this thrift-object to avro instead of converting it to int
4, the exception is thrown.
> {code}
> org.apache.avro.AvroRuntimeException: Unknown datum type java.lang.Byte: 4

> ----
> Proposed solution is also similar to AVRO-1500 - to overload {{getSchemaName}} in {{org.apache.avro.thrift.ThriftData}}
