[jira] [Created] (SPARK-2848) Shade Guava in Spark deliverables

Marcelo Vanzin created SPARK-2848:
-------------------------------------

             Summary: Shade Guava in Spark deliverables
                 Key: SPARK-2848
                 URL: https://issues.apache.org/jira/browse/SPARK-2848
             Project: Spark
          Issue Type: Sub-task
          Components: Spark Core
            Reporter: 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.
