Question 1

How do I set up a basic Cassandra cluster with CCM?

Accepted Answer

Run 'ccm create test -v 2.0.5 -n 3 -s' to create and start a 3-node cluster with Cassandra 2.0.5. Replace the version as needed, and CCM handles downloading, configuring, and starting the nodes locally.

Question 2

CCM vs Docker for Cassandra testing?

Accepted Answer

CCM offers Cassandra-specific controls like version switching and node operations, while Docker provides containerization for various services. CCM is better for detailed Cassandra simulation, but Docker is more portable and requires less manual network setup.

Question 3

How to debug Cassandra nodes using CCM?

Accepted Answer

Enable remote debugging with the '-d' flag during populate or '-r' when adding nodes, as shown in the README. For example, 'ccm populate -d -n 3' sets up debug ports on 2100, 2200, and 2300 for connecting a debugger.

Question 4

Does CCM support the latest Cassandra versions?

Accepted Answer

CCM allows specifying versions via binaries, source, or Git branches, but compatibility depends on project updates. Check the PyPI page or GitHub for recent releases, as older CCM versions might not support new Cassandra releases out-of-the-box.

Question 5

Can I use CCM to manage clusters on AWS or remote VPS?

Accepted Answer

Yes, use SSH options like --ssh-host and --ssh-username with CCM commands. For instance, 'ccm --ssh-host=192.168.33.11 create test -v 2.0.5 -n 3' deploys remotely, but ensure network connectivity and proper IP configuration.

Question 6

What are common issues when installing CCM on Mac?

Accepted Answer

Common issues include needing manual network aliases with ifconfig, as described in the README, and potential Python dependency conflicts. Refer to INSTALL.md for guidance, and consider persistent alias solutions for reboot scenarios.
