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

             Summary: AvroAsTextInput format creates invalid JSON for NaN values
                 Key: AVRO-1454
                 URL: https://issues.apache.org/jira/browse/AVRO-1454
             Project: Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.7.5
            Reporter: Antonio Piccolboni


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.
