Roman Mitasov updated AVRO-3966:
--------------------------------
Component/s: java
> toString generates poorly formatted defaults for bytes
> ------------------------------------------------------
>
> Key: AVRO-3966
> URL: https://issues.apache.org/jira/browse/AVRO-3966
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Reporter: Roman Mitasov
> Priority: Major
>
> Schema#toString and Protocol#toString both generate default values for
> "bytes" and "fixed" types.
> According to docs:
> {quote}Default values for bytes and fixed fields are JSON strings, where
> Unicode code points 0-255 are mapped to unsigned 8-bit byte values 0-255.
> Avro encodes a field even if its value is equal to its default.
> {quote}
> The following schema
> {code:json}
> {
> "type" : "record",
> "name" : "TestRecord",
> "fields" : [ {
> "name" : "testFixed",
> "type" : {
> "type" : "fixed",
> "name" : "Code",
> "size" : 3
> },
> "default" : "\u0009\u0020\u00FF"
> } ]
> }{code}
> If parsed and then again encoded to JSON would have {{"\t ÿ"}} value in
> "default".
> It happens because `toString` implementations use `JsonGenerator` with
> default escape configs.
