Hi, if you download Cassandra and look into "conf/cassandra.yaml" then you can see this:
"this keyspace definition is for demonstration purposes only. Cassandra will not load these definitions during startup. See http://wiki.apache.org/cassandra/FAQ#no_keyspaces for an explanation." So you should make all schema-related operation via Thrift/AVRO API, or you can use Cassandra CLI.
