----------------------------
Affects Version/s: (was: 1.7.7)
1.8.1
> Cannot define optional field tags in Avro schema
> ------------------------------------------------
>
> Key: AVRO-2134
> URL: https://issues.apache.org/jira/browse/AVRO-2134
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.8.1
> Reporter: raghugogi
> Priority: Major
>
> We are designing an Avro schema for kafka event payload and trying to use
> that for validating event message with Avro schema by posting to Kafka rest
> proxy.
> The avro schema has some fields which are defined with union encoding having
> null values
> {\"name\": \"address\", \"type\": ,[\"null\",\"string\"], default:null}
> Our clients want to send event message data to kafka broker for some complex
> data types optionally i.e. without JSON key/value even though it is specified
> in Avro schema or few of the primitive data types as optional within complex
> data type.
> Is there an avro version which can skip the validation for not sent field
> data in event message or payload for field specified in Avro schema?
> The error message we see as follows:
> "error_code": 42203,
> "message": "Conversion of JSON to Avro failed: Failed to convert JSON to
> Avro: Expected start-union. Got END_OBJECT"
>
