Ryan Blue commented on AVRO-1584:
---------------------------------
[~lemieud], thank you for your work to get this addressed! I think that the fix
we ended up with should fix the problem you were seeing since the control
characters will be properly escaped. If moving to base64 is important to you as
well, then I think the right way forward is to help standardize a different
JSON encoding, like Doug suggested for the long term. For now, I'm going to
mark this issue resolved since we've decided the way forward in the short term.
> Json output doesn't generate base64 for byte arrays

> Key: AVRO-1584
> URL: https://issues.apache.org/jira/browse/AVRO-1584
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.7.7
> Environment: Pure java.
> Reporter: Christophe Lorenz
> Attachments: AVRO-1584-Jackson-Base64-Default-Variant.patch,
> AVRO-1584.1.patch, AVRO-1584.patch
>
>
> The Json output of java generated code doesn't correctly encode byte arrays.
> Using this simple schema :
> {"namespace": "example.avro",
> "type": "record",
> "name": "ByteArrayEncoding",
> "fields": [ {"name": "data", "type": "bytes"} ]
> }
> The toString()
> System.out.println(new ByteArrayEncoding(ByteBuffer.wrap(new
> byte[]{0,31,65,66,67,(byte)255,(byte)182})));
> Returns raw bytes to string in the json :
> {"data": {"bytes": " ABC??"}}
> As a byte array is not tied to be a valid string, it should be converted back
> and forth to Base64 like other Json implementations :
> {"data": {"bytes": "AB9BQkP/tg=="}}
