我正在尝试用hadoop运行一个图像处理示例。
hadoop版本：hadoop 2.0.0-cdh4.2.1
hipi版本：hipi-2.1.0
opencv版本：opencv-2.4.11
opencv-2411.jar和hipi-2.1.0.jar在hadoop类路径中
我已经将“libopencv\u java2411.so”放在/etc/opencv/lib目录中。在/usr/lib/hadoop/libexec/hadoop-config.sh文件中设置java\u library\u path，指向opencv native library，如下所示：
java\u library\u path=${java\u library\u path}：/etc/opencv/lib
当我提交作业时，会收到以下错误消息。

attempt_201804241646_0001_m_000000_0: Native code library failed to load.
    attempt_201804241646_0001_m_000000_0: java.lang.UnsatisfiedLinkError: no opencv_java2411 in java.library.pathopencv_java2411

为什么无法加载本机库？请帮忙。
