-------------------------------
Summary: Protobuf to Avro - throw an exception of
"org.apache.avro.AvroRuntimeException: Malformed data. Length is negative: -25"
Key: AVRO-2912
URL: https://issues.apache.org/jira/browse/AVRO-2912
Project: Apache Avro
Issue Type: Bug
Components: java
Affects Versions: 1.9.2
Reporter: Nir Barel
Hi,
I tried to convert a protobuf bytes array into avro GenericRecord.
I used the avro-protobuf lib to generate the schema of my protobuf.
When I tries to convert my bytes array into GenericRecord I get an exception of
"org.apache.avro.AvroRuntimeException: Malformed data. Length is negative: -25"
Tried to debug this a bit, but couldn't tell why it fail on 1st field.
I double check my proto bytes array by converting it into protobuf object or
JSON and data is valid.
snip of my code:
{code:java}
Schema schema = ProtobufData.get().getSchema(Proto.class);
ProtobufDatumReader<Proto> datumReader = new
ProtobufDatumReader<>(Proto.class);
GenericDatumReader<GenericRecord> genericDatumReader = new
GenericDatumReader<>(datumReader.getSchema());
GenericRecord record = genericDatumReader.read(null,
DecoderFactory.get().binaryDecoder(new ByteArrayInputStream(bytes), null));
{code}
