Re: Roadmap for 4.0

I will commit time to test (not a full validation, but at least go through operations) regardless of the date. Both seems fine to me. Regards, Carlos Juzarte Rolo Cassandra Consultant / Datastax Certified Architect / Cassandra MVP Pythian - Love your data rolo@pythian | Twitter: @cjrolo | Skype

Re: Slowness in C* cluster after implementing multiple network interface configuration.

It might be a bug. Cassandra, AFAIK, scans those files for changes and updates the topology (So you don't need a restart if you change the files). It might be the case that the absence of the file, is still noticed by Cassandra even if it is not really used. I can do a small test to confirm, if so

Re: Can I replace a 2.0.9 node with a 2.1.14 node in a cluster?

Don't do that. In any case an upgrade between 2.0.x and 2.1.x is not so complex and difficult to do. And it is "downtime free". I would get the opportunity to do a full cluster upgrade. Regards, Carlos Juzarte Rolo Cassandra Consultant / Datastax Certified Architect / Cassandra MVP Pythian - Lo

Nodes failed to bootstrap, no nodetool info but system.peer populated.

Hi all, I just wanted to know if this should be worth filling a bug or not (Couldn't find any similar). I have a 3 node cluster (2.0.14). Decided to add 3 new ones. 2 failed because of hardware failure (virtualized environment). The process was automated, so what was supposed to happen was: - N
