Tatu Saloranta commented on FLINK-3855:
---------------------------------------
Also: if I am not mistaken, ElasticSearch2 connector does not actually use
jackson, just has a dependency, which looks like something that could be
removed (unless there's something wrong with transitive dependencies)?
Kafka connector has a small dependency (convenience binding).
> Upgrade Jackson version
> -----------------------

> Key: FLINK-3855
> URL: https://issues.apache.org/jira/browse/FLINK-3855
> Project: Flink
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.0.3
> Reporter: Tatu Saloranta
> Priority: Minor
>
> Jackson version in use (2.4.2) is rather old (and not even the latest patch
> from minor version), so it'd be make sense to upgrade to bit newer. Latest
> would be 2.7.4, but at first I propose going to 2.5.5.
> All tests pass, but if there are issues I'd be happy to help; I'm author of
> Jackson project.
