Qing Wang updated AVRO-2270:
----------------------------
Description:
Auto generated Avro schema with fields have union type including null, can not
be assigned to a non-null default value. The reason is Avro set null as the
first type in the union .see [the source code
|https://github.com/apache/avro/blob/master/lang/java/avro/src/main/java/org/apache/avro/reflect/ReflectData.java]
line 694 // add null as the _first_ type in a new union.
Based on [https://avro.apache.org/docs/1.8.1/spec.html#Unions], in a union, the
type of the default value must match the _first_ element of the union.
