Jonathan Eagles commented on YARN-6628:
---------------------------------------
So we are in a catch-22 since the version of fst the has the matching jackson
dependency has the incorrectly advertised license in the gpl (failing
rat-check). The version with the correct Apache License in the pom has the
newer jackson jars which are something we can't introduce in 2.8.
I tried what Jason suggested but I was unable to create a FSTConfiguration that
didn't trigger a class not found error for com.fasterxml.jackson.
Instead perhaps we shade the com.fasterxml jackson jar to not expose this to
the classpath.

> 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.
