将 pentaho 与 Jena Fuseki 连接时出错

Question

我正在尝试使用 pentaho 中的“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，并且我得到这个错误：

Error connecting to database [test]         :org.pentaho.di.core.exception.KettleDatabaseException: 
Error occurred while trying to connect to the database

Error connecting to database: (using class     org.apache.hive.jdbc.SparkSqlSimbaDriver)

我已经下载了 .jar 文件“jena-jdbc-driver-bundle-3.1.0.jar”（包含驱动程序到 Jena 连接）和“pentaho-big-data-kettle-plugins-hive.jar”（包含“ SparkSQLSimbaDriver" 类，该类看起来会导致错误），我已经尝试了一些东西：

• 将该 .jar 放入 Pentaho/data-integration/lib 中
• 创建一个新文件夹 Pentaho/data-integration/libext/JDBC 并将 .jar 放入其中。

在这两种情况下仍然出现相同的错误。

有人有任何想法或提示来解决它吗？ 最后，问题是如何将 Pentaho 与 Jena 连接起来。

谢谢！

Answer 1

要将 Pentaho 与 Jena 连接，您必须：

• 将“jena-jdbc-driver-bundle-3.1.0.jar”（它包含与 Jena 连接的驱动程序）放在 Pentaho/data-integration/lib/ 文件夹中

• 使用连接类型“通用”（在 Pentaho 中，当您创建新连接时）。大概，这就是问题的关键

• 在此连接中定义“jdbc:jena:remote:update=http://localhost:3030/name_of_dataset/update”（在我的情况下）如自定义连接 URL 和“org.apache.jena.jdbc.remote.RemoteEndpointDriver”如驱动程序类

...然后...去！！
