------------------------------------
[~exceptionfactory] I am planning to get back on this soon. You're welcome to
start, but I think I have time to get back into this.
> Upgrade Cassandra Components to Datastax 4 Driver
> -------------------------------------------------
>
> Key: NIFI-9770
> URL: https://issues.apache.org/jira/browse/NIFI-9770
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: David Handermann
> Priority: Major
>
> The Processors and Controller Services in the {{nifi-cassandra-bundle}}
> leverage the Datastax Driver version 3.10.2, which includes a transitive
> dependency on Google Guava 19.0. Older versions of Google Guava have several
> associated vulnerabilities, which do not appear to impact the Datastax Driver
> directly. In order to upgrade to a more recent version of Google Guava,
> however, it is necessary to upgrade to a recent version 4 release of the
> Datastax Driver. Datastax Driver 4.14.0 depends on Google Guava 25.0.
> The Datastax Driver version 4 supports access to Cassandra 2.1 and above, but
> upgrading the driver from version 3 to version 4 requires a number of
> changes. Several of the client configuration properties, accessible through
> NiFi component properties, must be provided through a different approach than
> the current driver configuration strategy. The Datastax Driver Upgrade Guide
> provides a summary of the relevant driver changes:
