-------------------------------------
Summary: C# UnionSchema fails to parse the the unions with same
type names with different namespaces
Key: AVRO-1363
URL: https://issues.apache.org/jira/browse/AVRO-1363
Project: Avro
Issue Type: Bug
Components: csharp
Affects Versions: 1.7.4
Reporter: Ramana Suvarapu
Attachments: reader.avpr
C# Union schema is unable to handle same type names with different namespaces.
It's throwing "SchemaParseException("Duplicate type in union: "...) exception.
In the below code, key of uniqueSchemas should be FullName of the type which is
similar to Java implementation.
internal static UnionSchema NewInstance(JArray jarr, PropertyMap props,
SchemaNames names, string encspace)
{
List<Schema> schemas = new List<Schema>();
IDictionary<string, string> uniqueSchemas = new Dictionary<string,
string>();
foreach (JToken jvalue in jarr)
{
Schema unionType = Schema.ParseJson(jvalue, names, encspace);
if (null == unionType)
throw new SchemaParseException("Invalid JSON in union" +
jvalue.ToString());
string name = unionType.Name;
if (uniqueSchemas.ContainsKey(name))
throw new SchemaParseException("Duplicate type in union: "
+ name);
uniqueSchemas.Add(name, name);
schemas.Add(unionType);
}
return new UnionSchema(schemas, props);
}
