Doug Cutting commented on AVRO-1126:
------------------------------------

> I would like to consider that in our API we don't use any JSON default values 
> at all [ ... ]

This might combine two things that are currently orthogonal (schema 
representation & data representation).  My instinct is to keep schemas 
independent of data representations.  A given JSON default value may have 
different representations in different data representations (generic, specific, 
reflect, protobuf, thrift, etc.). These are connected through the Json 
encoding.  A json default value can be converted to a particular data 
representation by decoding with a JsonDecoder and a DatumReader for the desired 
data representation.

Would you have this conversion done at Schema read time rather than at 
default-value access time, so that the same schema is represented differently 
for generic, specific & reflect?  Or do you have something else in mind?

> Quite annoyingly with Jackson 2+ the base package name has changed from 
> org.codehaus.jackson to com.fasterxml.jackson so in addition to changing the 
> dependencies from:
> {code:xml} 
> <dependency>
>     <groupId>org.codehaus.jackson</groupId>
>     <artifactId>jackson-core-asl</artifactId>
>     <version>${jackson.version}</version>
> </dependency>
> <dependency>
>     <groupId>org.codehaus.jackson</groupId>
>     <artifactId>jackson-mapper-asl</artifactId>
>     <version>${jackson.version}</version>
> </dependency>
> {code} 
> to:
> {code:xml} 
> <dependency>
>     <groupId>com.fasterxml.jackson.core</groupId>
>     <artifactId>jackson-core</artifactId>
>     <version>${jackson.version}</version>
> </dependency>
> <dependency>
>     <groupId>com.fasterxml.jackson.core</groupId>
>     <artifactId>jackson-databind</artifactId>
>     <version>${jackson.version}</version>
> </dependency>
> {code} 
> the base package in the code needs to be updated. More info can be found 
> [here|http://wiki.fasterxml.com/JacksonUpgradeFrom19To20], I am happy to do 
> the work just let me know what is preferable i.e. should I just attach a 
> patch to this issue?
