Alex Dettinger commented on SPARK-27932:
----------------------------------------
[~srowen] stated in [a somewhat related
PR|https://github.com/apache/spark/pull/24493] that it appears hard to upgrade
jackson-databind > 2.6 on spark 2.3.x, 2.4.x branches.
A key aspect to keep in mind is that jackson-databind introduced a behavior
change in 2.7 onward.
I propose to keep this ticket opened a bit of time in case someone could come
up with a bright idea.

> Project: Spark
> Issue Type: Task
> Components: Spark Core
> Affects Versions: 2.3.3, 2.4.3
> Reporter: Alex Dettinger
> Priority: Major
>
> SPARK-27051 has bumped jackson versions to 2.9.8, which is good.
> Would it be possible to upgrade the jackson version to >= 2.9.8 for
> spark-2.4.x, spark-2.3.x ?
> In case >= 2.9.8 is not possible, versions below would be ok too:
> * jackson >= 2.8.11.3
> * jackson >= 2.7.9.5
