> Hi
> When I use _logstash-codec-avro_schema_registry_,
> the following schema always raises an error for validating default.
> {code:java}
> // json
> {
> "type": "record",
> "name": "RawLog",
> ...
> "fields": [
> {
> "name": "exchangeRate",
> "type": "double",
> "default": 1.0
> },
> ...{code}
>
> This is an error message.
> {code:java}
> Error: Error validating default for exchangeRate: at . expected type double,
> got BigDecimal with value 0.1e1
> Exception: Avro::SchemaParseError
> Stack:
> /usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/avro-1.9.2/lib/avro/schema.rb:403:in
> `validate_default!'
> {code}
>
> It seems like the default value treated as BigDecimal, but it should be
> double.
> The plugin code - _logstash-codec-avro_schema_registry_ - ,
> they just simply use avro lib & schema registry,
> hard to find any proper reason why that make a validation error.
>
> If I put the BigDecimal as default value at validate_simple(),
> is it make a sense ?
> Please help me and reviews this patch.
>
> Thanks.
