我在windows机器上运行一个应用程序，它需要连接到在远程redhat机器上创建的配置单元表。我用的是javaspringboot。我正在尝试使用以下连接：

Connection connection = DriverManager.getConnection("jdbc:hive2://my_machine_hostname:10000/mydatabase", "my_username", "mypassword");

我得到一个错误：

java.sql.SQLException: Could not open client transport with JDBC Uri: 
    jdbc:hive2://my_machine_hostname:10000/my_database: 
    java.net.ConnectException: Connection timed out: connect

当我试图从另一台机器连接时，连接成功了。
