Subject [jira] [Created] (AVRO-1099) Int / Float cannot be decoded
Date Mon, 21 May 2012 23:22:42 GMT
John Jenkins created AVRO-1099:

             Summary: Int / Float cannot be decoded
                 Key: AVRO-1099
                 URL: https://issues.apache.org/jira/browse/AVRO-1099
             Project: Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.6.3
         Environment: Mac OS X 10.7.3. Eclipse IDE for Java EE Developers
            Reporter: John Jenkins
             Fix For: 1.7.0

I am currently using a JSON library that is encoding 0 for a double to "0" instead of "0.0",
without the quotes. First, I feel that "0" is a perfectly valid value for 0 as a double. But,
I tried to code around it by changing the "type" of the field to "["double", "int"]", without
the quotes and it is giving me this error:

Exception in thread "main" org.apache.avro.AvroTypeException: Expected start-union. Got VALUE_NUMBER_INT
	at org.apache.avro.io.JsonDecoder.error(JsonDecoder.java:697)
	at org.apache.avro.io.JsonDecoder.readIndex(JsonDecoder.java:441)
	at org.apache.avro.io.ResolvingDecoder.doAction(ResolvingDecoder.java:229)

	at org.apache.avro.generic.GenericDatumReader.read(GenericDatumReader.java:144)
	at org.apache.avro.generic.GenericDatumReader.read(GenericDatumReader.java:135)

If I change it to just "int", then it works for a few records until it reaches a double.

Thank you,
