Robert Stupp commented on CASSANDRA-7692:
-----------------------------------------

One solution would be to exclude the Java driver from $CASSANDRA_HOME/lib for 
the tools - e.g. introduce some "C* daemon internal lib dir".
I know [~norman] is working on [netty update 
(JAVA-352)|https://datastax-oss.atlassian.net/browse/JAVA-352] in the Java 
driver.

As soon as we use the Java driver in C* daemon classpath it might break 
embedded uses of C*.

IMO a proper solution would be to split the Java driver into separate modules 
and only use the "data related" part of it for CASSANDRA-7563.

[~slebresne], [~iamaleksey] any thoughts?

> UDFs (CASSANDRA-7563) requires Java Driver that supports User Types and new 
> collection features (at least Java Driver 2.1).
> May also be handled separately if e.g. Hadoop stuff requires this (follow-up 
> to CASSANDRA-7618).
