Can't say I've ever seen it do that without spitting something out to stdout. Can you try: 1. ps -A | grep java - to see if there is already a cassandra java process running for some reason 2. top - to see how much free memory you have before starting it up. If you can't commit 1GB the JVM won't be able to start 3. Start cassandra with the "-f" parameter to start it in the foreground -- might get you some better logging or a more obvious reaction: apache-cassandra-1.2.6/bin/cassandra -f 4. What version of Java are you running? It's recommended to run Oracle Java 6, though we've had development/QA-environment success with OpenJDK 6, not sure that we've ever tried Cassandra 1.2 with Java 7 (others may chime in with more experiences, though) Hope that helps, Branden > > Best regards, > > > David Torres > > > Computer Scientist > Renuda UK > > > tel: +44 (0)20 3371 1709 > web: www.renuda.com > > > Renuda UK is registered in England and Wales.
