Cassandra DB. com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table person

Question

The keyspace and 'person' table are exist

Hello, I'm new with Cassandra, so I'm just trying to execute select query from my java code, but I got an exception that the table is not exist (but it exists. Check the link above). Please help me figure out what could be a cause of this problem. Thank you in advance.

public class DS_Cassandra implements DS 
{
    Cluster cluster;
    Session session;
    private static final Logger log = Logger.getLogger( DS_Cassandra.class.getName() );

    public DS_Cassandra() 
    {
        cluster = Cluster.builder().addContactPoint("127.0.0.1").build();
        session = cluster.connect("testing");
    }

    @Override
    public ArrayList<Person> read() 
    {
        ArrayList<Person> list = new ArrayList<Person>();
        ResultSet results = session.execute("SELECT * FROM person"); //and here exception happened

Solution

Table names are case sensitive.
