Can you check if the jar you are submitting to the cluster contains a
different Guava than you use at compile time?

Also, it might happen that Guava is in your classpath, for example one some
YARN setups.

The last resort to resolve these issues is to use the maven-shade-plugin
and relocated the guava version you need into your own namespace.
