[Hawkular-dev] Cassandra and DataStax driver versions

[Peter Palaga]

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?
