Shawn Wu updated AVRO-3182:
---------------------------
Description:
Version: 1.10.2
When I use Avro in C#, I found Schema.ToString() for union schema will add an
extra *type* property in JSON string.
However, the correct union schema is a JSON array.
This is my test code in C#:
{code:java}
var columnCountSchema =
Schema.Parse("{\"type\":\"record\",\"name\":\"columnCount\",\"namespace\":\"avro.test.header\",\"fields\":[{\"name\":\"columnCount\",\"type\":\"int\"}]}");
var errorMessageSchema =
Schema.Parse("{\"type\":\"record\",\"name\":\"errorMessage\",\"namespace\":\"avro.test.header\",\"fields\":[{\"name\":\"errorMessage\",\"type\":[\"string\",\"null\"]}]}");
var schema = Schema.Parse($"[{columnCountSchema},{errorMessageSchema}]");
Console.WriteLine(schema.ToString());{code}
The actual output:
{code:java}
{"type":[{"type":"record","name":"columnCount","namespace":"avro.test.header","fields":[{"name":"columnCount","type":"int"}]},{"type":"record","name":"errorMessage","namespace":"avro.test.header","fields":[{"name":"errorMessage","type":["string","null"]}]}]}
{code}
The expected output:
{code:java}
[{"type":"record","name":"columnCount","namespace":"avro.test.header","fields":[{"name":"columnCount","type":"int"}]},{"type":"record","name":"errorMessage","namespace":"avro.test.header","fields":[{"name":"errorMessage","type":["string","null"]}]}]
{code}
