Hi,
If you don't mind the overhead you can make the conversion through the avro
binary data. So something like this should work (assuming both records are
using the same schema)
GenericRecord myRecord = ...
GenericDatumWriter<GenericRecord> writer = new
GenericDatumWriter<GenericRecord>(MyCustomRecord.getClassSchema());
ByteArrayOutputStream out = new ByteArrayOutputStream();
Encoder encoder = EncoderFactory.get().binaryEncoder(out, null);
writer.write(myRecord, encoder);
encoder.flush();
byte[] avroData = out.toByteArray();
out.close();
SpecificDatumReader<MyCustomRecord> reader = new
SpecificDatumReader<MyCustomRecord>(MyCustomRecord.class);
Decoder decoder = DecoderFactory.get().binaryDecoder(avroData, null);
MyCustomRecord myCustomRecord = reader.read(null, decoder);
