Julien Nioche commented on NUTCH-1477:
--------------------------------------
Found a clue in https://issues.apache.org/jira/browse/NUTCH-842. Not sure what
the point of compile-avro-schema is but we need to compile the schemas with
gora and not just avro. The generated classes now compile fine.
Using the modified schema fails at compilation as the generated objects don't
have accessors e.g. getContentType()
> NPE when injecting with DataFileAvroStore
