Description

See NUTCH-1477 for description.
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
