Awesome!

Can you describe the win here?

We are a bit conservative about dependencies as we often get burned with diamonds in the large builds of twitter internal projects.

I think you should be okay, as long as jackson uses semver, to use a later version with bijection-json (until 2.x.y). Are you seeing a problem that this fixes?

I ended up getting around the issue I was running into by passing the -Dmapreduce.task.classpath.user.precedence=true option into my hadoop job. I originally thought there was an issue between the internal twitter version (1.9.2) and this version but turns out it was a conflict between the jackson 1.8+ and the version of jackson running on some of the older hadoop clients (1.5.2). mapJson#invert depends on [JsonNode#getFields](http://jackson.codehaus.org/1.9.2/javadoc/org/codehaus/jackson/JsonNode.html#getFields(\)) which was introduced in version 1.8. Flipping the classpath works for me but isn't an ideal solution.

Since the fix was not related to upgrading to 1.9.2 feel free to close this pull request.

Thanks,
Michael

Sorry this sat so long. We are conservative with dependency upgrades.
