Subject [jira] [Commented] (YARN-6628) Unexpected jackson-core-2.2.3 dependency introduced
Date Tue, 18 Jul 2017 22:21:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6628?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16092274#comment-16092274

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?

> 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
