以下是一些在一臺機器上運行但在另一臺機器上失敗並出現異常的Avro代碼。Avro寫入和讀取在一臺機器上工作，而不是在其他機器上工作
我們無法確定這裏有什麼問題。
這是導致問題的代碼。
Class<?> clazz = obj.getClass();
ReflectData rdata = ReflectData.AllowNull.get();
Schema schema = rdata.getSchema(clazz);
ByteArrayOutputStream os = new ByteArrayOutputStream();
Encoder encoder = EncoderFactory.get().binaryEncoder(os, null);
DatumWriter<T> writer = new ReflectDatumWriter<T>(schema, rdata);
writer.write(obj, encoder);
encoder.flush();
byte[] bytes = os.toByteArray();
String binaryString = new String (bytes, "ISO-8859-1");
BinaryDecoder decoder = DecoderFactory.get().binaryDecoder(binaryString.getBytes("ISO-8859-1"), null);
GenericDatumReader<GenericRecord> datumReader = new GenericDatumReader<GenericRecord> (schema);
GenericRecord record = datumReader.read(null, decoder);
的例外是：
