Doug Cutting updated AVRO-1454:
-------------------------------
Attachment: AVRO-1454.patch
Here's a new patch to try that fixes a couple of issues with the earlier patch.
However from the description it looks like your schema is a record, which
should work with the earlier patch. This one should also work if the schema is
simply "float" or "double".
Can please you send a paraphrased version of your schema, with names changed
and other fields removed if needed? That might help.
Also, are you certain you tested with a patched Avro jar? If running on a
distributed cluster, did you make sure there were no other versions of Avro on
the classpath?

> The AvroAsTextInput format generates a record containing
> [omitted] , "someName": NaN}
> A json parser chokes on that and it is not legal JSON AFAIK. In related
> issues AVRO-972 and AVRO-1290 it is resolved, for lack of a better option, to
> map the value NaN to the string "NaN", which needs to be quoted in JSON. Our
> parser can handle that with no modifications, Java will parse such a string
> to the correct value using standard libraries.
