             Summary: Provide external way to construct Schema.Field with default value of 'null'
                 Key: AVRO-2369
                 URL: https://issues.apache.org/jira/browse/AVRO-2369
             Project: Apache Avro
          Issue Type: Task
          Components: java
            Reporter: Ivan Greene
             Fix For: 1.9.0


After making the Schema.Field constructor which takes the default value as a JsonNode was made package private, there is no external way to construct a field that has a default value of 'null'. Internally that constructor will call {{JacksonUtils.toJsonNode(defaultValue)}}, which will return 'null' when passed null, and the resulting Field will not have a default value (the json node would need to be NullNode instead of simply null itself). This will affect projects that need a way to dynamically build schemas and their fields.
