我正在尝试使用 AWS Glue 将数据从 EC2 实例中的 SQL Server 上传到 RedShift。
我已经创建了 Connections 和 Crawlers 并且它工作正常。
然后我创建了一个 Job 来加载我得到以下错误的数据。
驱动程序无法使用安全套接字层 (SSL) 加密建立与 SQL Server 的安全连接。错误：“sun.security.validator.ValidatorException：PKIX 路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径”。
