Jonathan Ellis resolved CASSANDRA-7358.
---------------------------------------
Resolution: Won't Fix
2.1 is using guava 16, but we aren't going to risk regressions by changing in a
2.0 minor release.
> Cassandra is still using guava 15
> ---------------------------------
>
> Key: CASSANDRA-7358
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7358
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Alexander Radzin
>
> The problem is that Cassandra still depends on guava 15 while CQL Driver
> depends on guava 16. Attempts to run both in the same process (that is
> typical for embedding cassandra e.g. for unit tests) causes incompatibility
> problems:

> This problem does not allow us to upgrade CQL driver to version newer than
> {{2.0.0-rc2}}.
