Question

我已经在KNOWAGE和Hortonworks论坛上问过这个问题，但没人能回答我=（（

好吧，我已经在Centos 7.5.1804，MySQL，JAVA等上安装了KNOWAGE（6.2.1_CE），一切运行正常，Oracle连接，MySQL连接，我可以使用这些数据库创建一些报告，一切都很好< / p>

接下来，我需要创建一个到Apache HIVE2的连接，因此我已经下载了HIVE JDBC驱动程序（从Hortonworks存储库中）* -standalone.jar（版本1.2.1000.2.6.2.0-205），在此之后，我使用Kerberos进行了一些测试，但最终建立了连接。

所以我在Ambari上检查了一些微小的SELECT，它工作正常，然后我试图在KNOWAGE上创建相同的SELECT，但它给我一个错误：

和在knowage.log中：

在这个问题上，您能给我个建议吗？我需要挖=）

不支持该方法（从“知道”到“ APACHE HIVE”）
