我一直在尝试通过 Spark 控制器 2.0 将 Vora 1.4 连接到 HANA 1.0 SPS12。可以将远程源添加到 HANA 工作室，但 Vora 表是不可见的。尝试刷新远程源时，Spark 控制器错误日志中出现类未找到错误。以下是错误消息：

任何人有任何想法？

为了解决这个问题，我卸载了 Spark 控制器 2.0 并安装了 Spark 控制器 1.6。Spark 控制器错误日志中没有更多错误消息。但问题仍然存在，Vora 表在 HANA 工作室的远程源中是不可见的。HANA 端的索引服务器日志也没有错误。似乎 Vora 1.4 与 Spark 控制器存在严重问题，因为 1.4 不在任何版本的 Spark 控制器兼容性矩阵中。我希望有人已经找到了解决此问题的方法。

我建议使用新的 VoraODBC 连接（又名 SAP HANA Wire 连接）将 HANA 连接到 Vora 1.4。这样可以轻松访问新的关系引擎和磁盘引擎中的表，而无需额外安装任何东西。

请参阅 Vora 1.4 开发人员指南章节“7.9 从 SAP HANA 访问 SAP Vora”（请参阅​​ https://help.sap.com/viewer/p/SAP_VORA）。
