Users of recent Linux distributions and Mac OS X Snow Leopard should be able to start up Cassandra simply by untarring and invoking `bin/cassandra -f` with root privileges. Snow Leopard ships with Java 1.6.0 and does not require changing the `JAVA_HOME` environment variable or adding any directory to your `PATH`. On Linux just make sure you have a working Java JDK package installed such as the `openjdk-6-jdk` on Ubuntu Lucid Lynx. == Step 4: Using cqlsh == - `bin/cqlsh` is an interactive command line interface for Cassandra.
