Describe the usage question you have. Please include as many useful details as possible.

I am new to arrow flight jdbc driver.
I have been doing some with flight sql protocol.
I have encountered this problem.

Mine code is kind of like this.

package org.example;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

// Press Shift twice to open the Search Everywhere dialog and type `show whitespaces`,
// then press Enter. You can now see whitespace characters in your code.
public class Main {

    public static void main(String[] args) throws Exception {
        Class.forName("org.apache.arrow.driver.jdbc.ArrowFlightJdbcDriver");
        Connection connection = DriverManager.getConnection("jdbc:arrow-flight-sql://192.168.0.220:33453/?useEncryption=false", "admin", "password");
        System.out.println("obtain connection ok");
        Statement statement = connection.createStatement();
        String str = "select 100;";
        ResultSet result = statement.executeQuery(str);
        System.out.println("execute query ok");
        while (result.next()) {
            int a = result.getInt(0);
            System.out.println(a);
        }
    }
}

I see this error msg
flight-jdbc.log

Caused by: cfjd.io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information: /10.233.105.111:3454
Caused by: java.net.ConnectException: Connection timed out: no further information

I don't know the host and port come from wired.
