Nevermind the question, I got code mostly working to do this on the sbt side.

> ---------------------------------
>                 Key: SPARK-2848
>                 URL:
>             Project: Spark
>          Issue Type: Sub-task
>          Components: Spark Core
>            Reporter: Marcelo Vanzin
>            Assignee: Marcelo Vanzin
> As discussed in SPARK-2420, this task covers the work of shading Guava in Spark deliverables
so that they don't conflict with the Hadoop classpath (nor user's classpath).
> Since one Guava class is exposed through Spark's API, that class will be forked from
14.0.1 (current version used by Spark) and excluded from any shading.
> The end result is that Spark's Guava won't be exposed to users anymore. This has the
side-effect of effectively downgrading to version 11 (the one used by Hadoop) for those that
do not explicitly depend on / package Guava with their apps.
