使用 SuperMap iObjects Spark 写出oracle数据源报错

0 投票

使用产品:SuperMap iObjects for Spark(版本10.0.1)、IManager。操作系统:windows10 64位

目前 iObjects支持读取和写出的数据源分别有哪些呢,在IOjects文档中经测试的不是特别准确,没有明确说明支不支持写出数据到oracle等形式的存储。

在使用SuperMap iObjects for Spark时,读取shp、csv、udb等数据源,写入Supermap Imanager中创建的oracle数据库中。

使用一些可视化工具如DataGrip和IDEA可以连接到数据库。

在本地进行测试,代码和报错如下:

定义了oracle的数据参数,想要将空间数据写入到oracle。有以下报错。

Exception in thread "main" java.lang.RuntimeException: Could not find a SpatialRDDProvider to process the params. at com.supermap.bdt.FeatureRDDProviderFactory$$anonfun$createProvider$2.apply(FeatureRDDProviderFactory.scala:19) at com.supermap.bdt.FeatureRDDProviderFactory$$anonfun$createProvider$2.apply(FeatureRDDProviderFactory.scala:19) at scala.Option.getOrElse(Option.scala:121) at com.supermap.bdt.FeatureRDDProviderFactory$.createProvider(FeatureRDDProviderFactory.scala:19) at com.supermap.bdt.FeatureRDDProviderFactory$.apply(FeatureRDDProviderFactory.scala:14) at com.dist.bdt.load.ToOracle$.main(ToOracle.scala:40) at com.dist.bdt.load.ToOracle.main(ToOracle.scala)

//读取oracle数据报错如下

您好,读取的类型在文档第三章节中有详细的描述,其次这些类型只要在我们iDesktop中能导入读取,一般都是支持的;这个报错应该是读取的arcsde的数据,我spark组件暂时不支持
