> 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.
