------------------------------------
Summary: `AvroRecordSchema().toRowFunction` throws an NPE when
avro record contain nulls
Key: BEAM-6742
URL: https://issues.apache.org/jira/browse/BEAM-6742
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Affects Versions: 2.9.0
Reporter: Julien Tournay
When generating a {{SerializableFunction[SomeClass, Row]}}
where {{Someclass}} was generated and has nullable fields, the generated
function will throw a NPE.
For example given the following avro schema:
{code:java}
{
"type": "record",
"name": "TestRecord",
"namespace": "com.spotify.scio.avro",
"doc": "Record for testing",
"fields": [
{"name": "int_field", "type": ["null", "int"], "default": null},
{"name": "long_field", "type": ["null", "long"], "default": null},
{"name": "float_field", "type": ["null", "float"], "default": null},
{"name": "double_field", "type": ["null", "double"], "default": null},
{"name": "boolean_field", "type": ["null", "boolean"], "default": null},
{"name": "string_field", "type": ["null", "string"], "default": null},
{"name": "array_field", "type": {"type": "array", "items": "string"},
"default": null}
]
}
{code}
the following code witl throw:
{code:java}
val clazz =
classTag[avro.TestRecord].runtimeClass.asInstanceOf[Class[avro.TestRecord]]
val toRow = new AvroRecordSchema().toRowFunction(TypeDescriptor.of(clazz))
avroWithNullable.map(x => toRow(x)).foreach(println)
{code}
Stacktrace:
