Matt Burgess commented on NIFI-3915:
------------------------------------
As far as I can tell, Kerberos support for Cassandra is only available via a
vendor (DataStax Enterprise), they have their own fork of the Apache Cassandra
driver, which does appear to be Apache 2.0-licensed. However their transitive
dependencies are of different (older) versions than the current version of the
driver included with the NiFi Cassandra processors (driver version 3.0.2). I'm
worried that switching to 1.0.6-dse or some other non-Apache-based version
could cause problems for those using Apache Cassandra clusters.
Perhaps an initial approach is to parameterize the version for
cassandra-driver-core in nifi-cassandra-processors/pom.xml. Then, as long as
the driver is truly a drop-in replacement, you could build the
nifi-cassandra-bundle overriding that property with a vendor-specific version.
Having said that, you would also need to add a processor property (to
AbstractCassandraProcessor) for the JAAS Client App name, and some way to use
the alternative AuthProvider (perhaps a AuthProvider Class Name property,
defaulted to empty or the Apache Cassandra default AuthProvider class). I'm a
bit leery of adding these properties to Apache NiFi when they can only be used
with a vendor's product, but there is precedence for it (Shield/X-Pack
properties for the Elasticsearch processors, e.g.).
Any thoughts on this? I am welcome to all comments, questions and suggestions :)
