Question

在提供JDBC URL格式后，我想使用JDBC连接选项将数据从Glue加载到SQL Server中

jdbc:sqlserver://host:port;databaseName=db_name, User name, and Password

，在测试连接时，出现以下错误。谁能帮助我我哪里出错了？

2019-11-13 09:29:01 INFO  CatalogClient:682 - Got connection 'SQLServer' info from Catalog with url: jdbc:sqlserver://32.238.81.66:1433/Glue_Test

Check that your connection definition references your JDBC database with correct URL syntax, username, and password. The TCP/IP connection to the host 32.238.81.66, port 1433 has failed.

 Error: "Connection timed out: no further information. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.". Exiting with error code 30

胶水连接的工作方式与允许在任何VPC中进行通信的方式非常相似。 Glue将启动一个弹性网络接口，以促进与数据库的通信。您可以测试的第一件事是，在与数据库相同的子网和安全组中启动实例，然后执行“ nc -vz dbendpoint port”。这可以确认，如果您可以成功建立连接，则安全组允许在该端口上进行通信。

从胶水使用相同的子网和安全组，这应该没有问题。您也可以以此为参考：https://docs.aws.amazon.com/glue/latest/dg/start-connecting.html
