------------------------------

             Summary: ProtobufDataWriter fails when enum value is UNRECOGNIZED
                 Key: AVRO-3099
                 URL: https://issues.apache.org/jira/browse/AVRO-3099
             Project: Apache Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.10.1
            Reporter: Dan Hill


This happens when the Java job with the protobuf writer has an older version of the protobuf class but receives protobuf data containing new, unrecognized enum values.  When I print out the enum's toString, it returns 'UNRECOGNIZED'.
