Nandor Kollar created AVRO-2086:
-----------------------------------
Summary: 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
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}
