Question

我正在尝试通过RJDBC软件包访问athena，但我不断收到以下错误消息：

.jclassLoader()$setDebug(1L) 

drv <- JDBC(driverClass = "com.amazonaws.athena.jdbc.AthenaDriver",
            "C:/Users/falvarenga/Downloads/AthenaJDBC42_2.0.7.jar",
            identifier.quote="'")

RJavaClassLoader: added 'C:/Users/falvarenga/Downloads/AthenaJDBC42_2.0.7.jar' to the URL class path loader
RJavaClassLoader: adding Java archive file 'C:/Users/falvarenga/Downloads/AthenaJDBC42_2.0.7.jar' to the internal class path
RJavaClassLoader: added 'C:/Users/falvarenga/Documents/R/R-3.5.3/library/RJDBC/java/RJDBC.jar' to the URL class path loader
RJavaClassLoader: adding Java archive file 'C:/Users/falvarenga/Documents/R/R-3.5.3/library/RJDBC/java/RJDBC.jar' to the internal class path
RJavaClassLoader@33909752.findClass(com.amazonaws.athena.jdbc.AthenaDriver)
 - URL loader did not find it: java.lang.ClassNotFoundException: com.amazonaws.athena.jdbc.AthenaDriver
RJavaClassLoader.findClass("com.amazonaws.athena.jdbc.AthenaDriver")

   Directory, can get 'C:\Users\falvarenga\Documents\R\R-3.5.3\library\rJava\java\com\amazonaws\athena\jdbc\AthenaDriver.class'? NO

    >> ClassNotFoundException

我在这里想念什么？

我创建了AWR.Athena软件包来管理使用DBI + rJava时的jar / classpath设置，您可以尝试一下。

install.packages("AWR.Athena")

RJDBC找不到驱动程序类
