Unable to connect to MySQL cluster database I am unable to connect to mysql cluster database after starting my management node, data node, mysql node. I made the necessary changes by adding the loadbalance in the dbURL. But I am not able to access the connection. The mysqld port is 1186. Please assist. 

String dbURL = "jdbc:mysql:loadbalance://localhost/bank";
String dbDriver = "com.mysql.jdbc.Driver";
private Connection dbCon;
public boolean connect() throws ClassNotFoundException, SQLException {
        Class.forName(dbDriver);

        // login credentials to your MySQL server
        dbCon = DriverManager.getConnection(dbURL, "root", ""); 
        return true;
    }


The error I am getting when I try to log in is: 


  javax.servlet.ServletException:
  com.mysql.jdbc.exceptions.jdbc4.CommunicationsException:
  Communications link failure


How do I test MySQL cluster database? I managed to login using the following in command prompt. Please assist. 


  mysql -h 127.0.0.1 -P5000 -u root
It looks like your MySQLD is running at port 5000, from the working mysql command line.
  The server listening on port 1186 is probably the cluster management server (ndb_mgmd).  It has its own client (ndb_mgm).  You cannot connect to it using the mysql client.  Similarly, the MySQL JDBC driver cannot connect to it.
