> Key: AVRO-1037
> URL: https://issues.apache.org/jira/browse/AVRO-1037
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.6.2
> Reporter: Scott Carey
> Assignee: Scott Carey
> Fix For: 1.6.3

> Attachments: AVRO-1037.patch

> AVRO-972 uses a method on JsonNode that was introduced with Jackson 1.6.0.  \
> Unfortunately, Hadoop in a distributed environment places jackson on the mapreduce \
> classpath prior to a user's Jar. Avro should function when this happens.
> There are two things we are using that are new in Jackson 1.6.0 -- \
> JsonNode.getValueAsDouble()  and MinimalPrettyPrinter MinimalPrettyPrinter is OK \
> because the class is new, and if there is a Jackson 1.5.x jar on a classpath before \
> one that is >= 1.6.0, it will find the class in the second jar.  We need to avoid \
> JsonNode.getValueAsDouble() however.  There is a replacement that is equivalent and \
> existed prior, JsonNode.getDoubleValue().
