Nodes do not join about ccm HOT 3 CLOSED

Not sure what to tell you, but I can't reproduce your situation. It did made me notice that --vnodes command was not correctly taken into account (it worked correctly with the shortcut "ccm create test -v 1.2.5 -n 3 --vnodes -s", but not with populate used separately). I've just pushed a simple fix for that. But even with that "bug", the exact same command than above work correctly on my box. I do am on linux however but unfortunately I don't have a Mac to test on that.

The first thing you could do is make sure you're using a recent version of ccm. Then you can try deleting ~/.ccm to make sure you start from a clean state. If it's still not working, maybe have a look at the log files (you can use "ccm showlog node1" or go check in ~/.ccm/test/node1/logs directly) and check in all the ~/.ccm/test/nodeX/conf/cassandra.yaml if the seeds are set (the first node will have just himself, the 2nd node will have 1 and 2, and the third node will have all nodes as seeds (which is slightly unconventional but works and was just slightly simpler for ccm)).

Thanks Sylvain, I tried a few different combinations of starting a cluster (everything from the create/populate/start form the readme, through create/add/start and create with --start), they behaved a bit differently. When I used create/populate/start the nodes started, but did not form a cluster, but when I did create with --start only the first node started, and the command hanged. One of the times I tried this I saw a familiar error in the logs, and exception about the snappy extension. I've had problems before with Cassandra on OS X where the snappy library shipped isn't compatible, and causes startup errors. When I swapped in a more recent version of snappy everything worked.

Btw. ccm start --verbose didn't output anything when I ran the setups that just hung, even though it managed to start a Cassandra node.

Not sure why Snappy problems can cause this, but since you've resolved your problem I'm going to call it a day on this issue.
