Alfonso Nishikawa commented on GORA-174:
----------------------------------------
@Julien: after analyzing your test classes patch, I think they work as
expected: before your changes, the class WebPage exists, and method
WebPage#setContent() too. After your patch, without regenerating the class
WebPage, the method WebPage#setContent() too, so WebPage#setContent(null) will
not fail. DataFileAvroStore success writing a null. No problem.
To make it fail must: modify webpage.json, regenerate WebPage, and will not
compile because the method WebPage#setContent() will not exist.
> GORA compiler does not handle ["string", "null"] unions in the AVRO schema

> 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
