Herman van Hovell commented on SPARK-23897:
-------------------------------------------

This is a duplicate or SPARK-23854.

We are not going to upgrade Guava any time soon. This is notoriously hard to do 
because it is used in a lot Spark's dependencies and the guava developers 
aggressively remove deprecated APIs; updating can easily break stuff (missing 
methods that sort of thing). See the discussion in 
[https://github.com/apache/spark/pull/20966]  for some more context.
