Now let's try to read and write some data using the command line client.
- * bin/cassandra-cli --host localhost --port 9160
+ * bin/cassandra-cli --host localhost
The command line client is interactive so if everything worked you should
be sitting in front of a prompt...

As the banner says, you can use 'help' or '?' to see what the CLI has to
offer, and 'quit' or 'exit' when you've had enough fun. But lets try
something slightly more interesting...

If your session looks similar to what's above, congrats, your single node
cluster is operational! But what exactly was all of that? Let's break it
down into pieces and see.
- set Keyspace1.Standard2['jsmith']['first'] = 'John'
- \ \ \ \ \
- \ \ \_ key \ \_ value
- \ \ \_ column
- \_ keyspace \_ column family

-Data stored in Cassandra is associated with a column family (Standard2),
+Data stored in Cassandra is associated with a column family (Users),
which in turn is associated with a keyspace (Keyspace1). In the example
above, we set the value 'John' in the 'first' column for key 'jsmith'.
