import java.sql.*;

public class Sample2

    public static void main (String [] args)
    throws ClassNotFoundException
    {
        // Teradata Type 4 JDBC Driver
        String url = "jdbc:teradata://X.X.X.X/";

        try
        {
            // Load the Teradata Driver
            Class.forName ("com.teradata.jdbc.TeraDriver");

            // Connect to the Teradata database specified in the URL
            // and submit userid and password.
            System.out.println("Connecting to " + url);

			Connection con =  DriverManager.getConnection(url, props);

            System.out.println("Established successful connection");

            con.close();
            System.out.println("Disconnected");
        }
        catch (SQLException ex)
        {
            // A SQLException was generated.  Catch it and display
            // the error information.
            // Note that there could be multiple error objects chained

            System.out.println();
            System.out.println("*** SQLException caught ***");

            while (ex != null)
            {
                System.out.println(" Error code: " + ex.getErrorCode());

                System.out.println(" Message: " + ex.getMessage());
                ex.printStackTrace();
                System.out.println();
                ex = ex.getNextException();
            }

            throw new IllegalStateException ("Sample failed.") ;
        }
    }
}

I am using :
JDBC version : TeraJDBC__indep_indep.15.10.00.14
Teradata version : 15.00
 
And I got this error:

*** SQLException caught ***
