-------------------------------------------------------------------
This issue is to support single type Unions within Avro schemas. AFAIK we have
committed support for this within all modules in the GORA_174 datastore.
Recursive nested structures and multi-type Union support are different issues
and they are confusing this parent issue very much.
Unless there is strong argument I propose to close this issue as resolved as
well as all children issues relating only to single type union support within
Avro schemas.
Regarding support for multiple union type support and the recursive issue we
should open and address these issues elsewhere.

> We are getting NPE when using the DataFileAvroStore, in order to avoid that I
> modified the schema to allow for null values on some fields e.g. {"name":
> "baseUrl", "type": ["string", "null"] }
> however when generating the code for the schema the accessors are not
> generated by GORA which prevents Nutch from compiling
