------------------------------
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'.
