-----------------------------------
Assignee: Nandor Kollar
> Can't create specific record with a single Decimal field with default value
> ---------------------------------------------------------------------------
>
> Key: AVRO-2086
> URL: https://issues.apache.org/jira/browse/AVRO-2086
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.8.2
> Reporter: Nandor Kollar
> Assignee: Nandor Kollar
>
> Given a simple record schema with a single byte field annotated with Decimal
> logical type and has default value set:
> {code}
> {
> "type":"record",
> "name":"TestRecordWithDecimalFieldWithDefault",
> "namespace":"org.apache.avro.specific",
> "fields":[
> {
> "name":"f1",
> "type":{
> "type":"bytes",
> "logicalType":"decimal",
> "precision":9,
> "scale":2
> },
> "default":"0.00"
> }
> ]
> }
> {code}
> compiled with
> {{avro-tools compile -bigDecimal schema
> TestRecordWithDecimalFieldWithDefault.avsc .}}
> The following test case (which should use the decimal's default value):
> {code}
> @Test
> public void testRecordWithDecimalLogicalTypeWithDefault() throws
> IOException {
> SpecificData.get().addLogicalTypeConversion(new
> Conversions.DecimalConversion());
> TestRecordWithDecimalFieldWithDefault record =
> TestRecordWithDecimalFieldWithDefault.newBuilder().build();
> File data = write(TestRecordWithDecimalFieldWithDefault.getClassSchema(),
> record);
> List<TestRecordWithDecimalFieldWithDefault> actual = read(
> TestRecordWithDecimalFieldWithDefault.getClassSchema(), data);
> assertEquals(new BigDecimal(0.00).setScale(2), actual.get(0).getF1());
> }
> {code}
> fails with
> {code}
