Jonathan Eagles commented on YARN-6628:
---------------------------------------
[~jlowe], this patch YARN-6628.3-branch-2.8.patch works for both branch-2 and
branch-2.8.
For branch 2.8, this patch totally removes (by shading) jackson 2 and fst from
user exposure.
For branch 2, there are new uses of jackson 2 in hdfs.
I want to unblock the 2.8.2 release, but I want to make sure jackson 2 is
remove from HDFS as well.
> Unexpected jackson-core-2.2.3 dependency introduced

> Key: YARN-6628
> URL: https://issues.apache.org/jira/browse/YARN-6628
> Project: Hadoop YARN
> Issue Type: Bug
> Components: timelineserver
> Affects Versions: 2.8.1
> Reporter: Jason Lowe
> Assignee: Jonathan Eagles
> Priority: Blocker
> Attachments: YARN-6628.1.patch, YARN-6628.2-branch-2.8.patch,

> The change in YARN-5894 caused jackson-core-2.2.3.jar to be added in
> share/hadoop/yarn/lib/. This added dependency seems to be incompatible with
> jackson-core-asl-1.9.13.jar which is also shipped as a dependency. This new
> jackson-core jar ends up breaking jobs that ran fine on 2.8.0.
