Michael Pershyn created AVRO-1564:
-------------------------------------
Summary: Unknown datum type exception while converting optional
bytes using avro-thrift
Key: AVRO-1564
URL: https://issues.apache.org/jira/browse/AVRO-1564
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.7.7
Reporter: Michael Pershyn
Assignee: Michael Pershyn
Very similar to AVRO-1500.
When in thrift schema (e.g. {{Test}}) with optional byte field:
{code}
16: optional byte byteOptionalField
{code}
And it is initialized like:
{code}
test.setByteOptionalField((byte)4);
{code}
Then during conversion of this thrift-object to avro instead of converting it
to int 4, the exception is thrown.
{code}
org.apache.avro.AvroRuntimeException: Unknown datum type java.lang.Byte: 4

Proposed solution is also similar to AVRO-1500 - to overload {{getSchemaName}}
in {{org.apache.avro.thrift.ThriftData}}
