---------------------------------
Resolution: Duplicate
> upgrade to jackson 2.14.3
> -------------------------
>
> Key: HADOOP-19230
> URL: https://issues.apache.org/jira/browse/HADOOP-19230
> Project: Hadoop Common
> Issue Type: Task
> Components: common
> Reporter: PJ Fanning
> Priority: Major
> Labels: pull-request-available
>
> Follow up to HADOOP-18332
> I have what I believe fixes the Jackson JAX-RS incompatibility.
> https://github.com/pjfanning/jsr311-compat/
> The reason that I want to start by just going to Jackson 2.14 is that Jackson
> has new StreamReadConstraints in Jackson 2.15 to protect against malicious
> JSON inputs. The constraints are generous but can cause issues with very
> large or deeply nested inputs.
> Jackson has had a lot of security hardening fixes recently and it seems
> problematic to be stuck on an unsupported version of Jackson (2.12).
