你好
我现在想使用SDXReader.readFromDS读取存放在oracleplus里面的sdx+数据，想请问下如何进行访问，我使用如下方法，一直报错
val dsConnInfo = DSConnectionInfo(DatasourceType.OraclePlus,"10.10.0.249:1521/orcl", "C_JCDL_530000", "", Some("C_JCDL_530000"), Some("xxxx"))
val rdd = SDXReader.readFromDS(sc, dsConnInfo,"HYDA", numSlices = 1, isDriver = false)
报错错信息是
[bdt]: open datasource 10.10.0.249:1521/orcl failed
Exception in thread "main" java.lang.IllegalArgumentException: dataset is null
