Subject [jira] [Commented] (GORA-174) GORA compiler does not handle ["string", "null"] unions in the AVRO schema
Date Sun, 18 Nov 2012 21:36:58 GMT

----------------------------------------

Hi, Julien.
Try the patch and tell me if it solves your problem (I tested, but who knows...).
You will find when using optional fields (those unions with "null") that you will get the
exception in GORA-183 if you leave a field=null. Will try to fix it soon.

> 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
