Jason Lowe commented on YARN-6628:
----------------------------------
Thanks for the patch!
Shading is far from my first choice, but it seems like we have little other
choice unless we can remove the fst dependency completely since we're stuck
between a mandatory license upgrade and a mandatory jackson-2 dependency.
There are some "com.yahoo" prefixes in the shading directives that need to be
updated. Also have you verified that shading didn't pick up any undesired
settings for META-INF or other items in the jar that could be problematic?
> 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,
> YARN-6628.3-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.
