Alexander Radzin commented on CASSANDRA-7358:
---------------------------------------------
Johathan, I understand your reasons. However the problem is that right now this
problem blocks upgrade of CQL driver to stable release that contains a bunch of
bug fixes.
> Conflict between guava from Cassandra and CQL Driver
> ----------------------------------------------------

> 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:
