Nandor Kollar updated AVRO-2032:
--------------------------------
Description:
When using the JsonEncoder to serialize Double.NaN, Double.POSITIVE_INFINITY or
Double.NEGATIVE_INFINITY to resulting JSON cannot be parsed by the JsonDencoder.
An AvroTypeException is thrown with the message "Expected double. Got
VALUE_STRING".
When using BinaryEncoder/BinaryDecoder, it works fine.
This JUnit code snippet will reproduce the issue:
{code}
@Test
public void test() throws Exception {
Schema schema = SchemaBuilder.builder()
.record("record")
.fields()
.optionalDouble("number1")
.optionalDouble("number2")
.optionalDouble("number3")
.endRecord();
GenericData.Record record = new GenericData.Record(schema);
record.put("number1", Double.NaN);
record.put("number2", Double.POSITIVE_INFINITY);
record.put("number3", Double.NEGATIVE_INFINITY);
ByteArrayOutputStream out = new ByteArrayOutputStream();
JsonEncoder encoder = EncoderFactory.get().jsonEncoder(schema, out);
new GenericDatumWriter<GenericRecord>(schema).write(record, encoder);
encoder.flush();
System.out.println(out);
Decoder decoder = DecoderFactory.get().jsonDecoder(schema,
out.toString());
GenericData.Record deserialized = new GenericData.Record(schema);
new GenericDatumReader<GenericRecord>(schema).read(deserialized,
decoder);
}
{code}
