rhive.connect（）与MapR分发有关的问题

在加载和初始化RHive（使用RHive.init（））之后，我在RHive.connect（）中遇到以下错误：

如果运行rhive.env（），我会收到以下警告/错误：

现在，rhive.connect（）返回以下错误：

你知道我错在哪里吗？谢谢

Java找不到dll库。启动应用程序时，必须将java.library.path属性设置为指向要加载的dll` 试试这样的

java -Djava.library.path=/opt/mapr/hadoop/hadoop-0.20.2/lib/native/

谢谢，成功了；我的意思是，我现在遇到了一个不同的错误。在本机文件夹之后，您有什么。您的操作系统和archi中必须有另一个文件夹依赖项。。

export LD_LIBRARY_PATH=/opt/mapr/hadoop/hadoop-0.20.2/lib/native/Linux-amd64-64/
