Wei-Chiu Chuang commented on HADOOP-17014:
------------------------------------------
I don't think jackson-databind 2.10 is incompatible as far as hadoop's usage
goes.
However, the 2.10 adds additional dependency and my PRs for branch-3.2 and
branch-3.1 fails shading because of the extra classes added by it. I am ok to
update to 2.9.10.4 to unblock the Hadoop 3.1.4 release. But in the long run
this is not sustainable.
> Upgrade jackson-databind to 2.9.10.4

> trunk (3.3.0) now has HADOOP-16905. But branch 3.2/3.1/.. still uses
> jackson-databind 2.9.
> I'm opening this jira since I'm unsure whether we are backporting
> HADOOP-16905 to lower version branches due to compatibility concern or
> whatever.
