关于jdbc：连接pentaho与Jena Fuseki时出错

我正在尝试在pentaho中使用"连接类型：SPARKSQL "(以及localhost，端口和DBname)创建从pentaho(7.0.0.0-25)到Jena(fuseki 2.4.1)的连接，并且出现此错误：

我已经下载了.jar文件" jena-jdbc-driver-bundle-3.1.0.jar "(包含与Jena连接的驱动程序)和" pentaho-big-data-kettle-plugins-hive.jar "(包含" SparkSQLSimbaDriver "类，该类看起来像是引起错误)，并且我尝试了一些方法：

  • 将该.jar放在Pentaho / data-integration / lib中
  • 要创建一个新文件夹Pentaho / data-integration / libext / JDBC并在其中放入.jar。

在两种情况下仍然出现相同的错误。

有人有什么想法或提示要解决吗？？
最后，问题是我如何将Pentaho与Jena连接起来。

谢谢！

要将Pentaho与Jena连接起来，您必须：

  • 在文件夹Pentaho / data-integration / lib /

    中放入" jena-jdbc-driver-bundle-3.1.0.jar"(其中包含与Jena连接的驱动程序)

  • 使用连接类型"通用"(在Pentaho中，当您创建新连接时)。可能就是问题的关键

  • 在这种情况下，

    定义" jdbc：jena：remote：update = http：// localhost：3030 / name_of_dataset / update"(在我的情况下)，例如自定义连接URL和" org.apache.jena.jdbc.remote" .RemoteEndpointDriver"，例如驱动程序类

...然后...去!!
