---------------------------------
Summary: Provide way to distinguish whether a Schema.Field has a
default value or its default is null
Key: AVRO-2368
URL: https://issues.apache.org/jira/browse/AVRO-2368
Project: Apache Avro
Issue Type: Task
Components: java
Reporter: Ivan Greene
Fix For: 1.9.0
After making {{Schema.Field#defaultValue}} package private, there is no way to
distinguish whether a Field has a default value of 'null' or has no default at
all. This is a breaking change, notably affecting Hortonworks Schema Registry.
See discussion here: [https://github.com/hortonworks/registry/pull/547]
I propose we should make that method public and still deprecated. Otherwise I
don't see a clear way to release a version of the Hortonworks registry that
will be compatible with both Avro 1.8.x and 1.9.0.
