Question

我是R编程的新手。我正在尝试使用rhive.connect()连接到配置单元。我知道“org.apache.xerces.jaxp.DocumentBuilderFactoryImpl”解析器可能存在一些不匹配。我该如何解决这个问题？

ERROR conf.Configuration: Failed to set setXIncludeAware(true) for parser org.apache.xerces.jaxp.DocumentBuilderFactoryImpl@1f9bb21f:java.lang.UnsupportedOperationException:  setXIncludeAware is not supported on this JAXP implementation or earlier: class org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

Error: Failed to connect to hdfs://localhost:9000.

如果我的理解是错误的，请帮助我理解。

我注意到/usr/lib64/R/etc/Makeconf文件正在尝试使用R CMD javareconf命令生效。 Makeconf的配置文件是R吗？

感谢。

我遇到了同样的问题，我在R命令行下面运行解决了：

.jcall("java/lang/System","S","setProperty","javax.xml.parsers.DocumentBuilderFactory","com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl")

rhive.connect（）抛出异常
