Thanks for sharing the news, John.
That PR in hawkular-parent is mine. I was motivated by seeing Juca to
use driver 2.2.0-rc3 in Accounts.
OK, I'll upgrade the driver to the newest major version, next time it
comes under my hands.
A related topic: Juca has recently created C+ driver module in
hawkular-common [1]. The motivation is that ATM, pretty much every HK
component is using the c* driver and pretty much every HK component is
packaging the driver into its war/ear thus unnecessarily increasing the
size of the HK main distro. With this new module the components can
assume the driver is provided and do not need to include it in their
wars/ears. Does anybody have a problem with this approach?

There is a PR[1] open for hawkular-parent that upgrades Cassandra
from
2.2.0 to 2.2.2 and the driver from 2.2.0-rc2 to 2.2.0-rc3, so now is a
good time to discuss this.
Earlier this week, Cassandra 3.0 was
released[2]. There are some substantial changes including a rewrite of
the storage engine to be better optimized for CQL, materialized views,
and range deletes to name a few. The driver repo has been maintaining
separate branches for each Cassandra branch which has been causing a lot
of maintenance overhead. It was announced earlier today on the driver
mailing list that the 2.2 branch, which we are currently using, has been
merged into the 3.0 branch[3]. There will be no further development on
the 2.2 branch. The driver is designed to be backwards compatible such
that newer versions of the driver can be used with older versions of
Cassandra. This means we could upgrade the driver without upgrading
Cassandra; however, I think it makes sense to upgrade Cassandra as well.
Are there any questions, comments, concerns, objections, etc.?
