getting the connection with cassandra hector api 0.7

Basic Configuration and Setup
The main entry point for accessing a Cassandra instance through Hector is the Keyspace class. All of the implementations in the api package rely on a Keyspace for interfacing with Cassandra. An instance of Keyspace can be retrieved using the default configurations with very little code:
Cluster cluster = HFactory.getOrCreateCluster("TestCluster",
new CassandraHostConfigurator("localhost:9160"));
Keyspace keyspace = HFactory.createKeyspace("Keyspace1", cluster)
The underlying HConnectionManager as well as the host-specific pool for localhost:9160 will both be created automatically if they do not already exist. Once a handle to the Keyspace has been obtained, you will probably spend most of your time using HFactory to construct the query appropriate to your use case. Unlike previous versions of the Hector client, the classes returned from HFactory all support method chaining that keeps code compact and more legible.
The Cluster implementation returned from HFactory is designed as a thread-safe class and can be a long-lived object. However, instances of Cluster are held be HFactory internally once created, so using the getOrCreateCluster method repeatedly as outlined above is harmless.
A point to note for users of earlier versions of Hector, is that the meaning of Keyspace has changed significantly. The previous interface and class (Keyspace and KeyspaceImpl respectively) are now embodied in KeyspaceService for a more consistent naming scheme. KeyspaceService is not thread-safe and should be treated as a short-lived, lightweight object.
