I downloaded the latest RC2 to play with. I was able to convert my 0.6 storage-conf.xml using the conversion tool. 0.7rc2 started up just fine for me and I was able to connect to it using the CLI.
When I run "show keyspaces;" command I don't see the keyspaces I've defined. I'm probably missing something simple. Do I need to modify the generated cassandra.yaml file? thanks peter
