我在hadoop工作，突然间我为我的图像处理程序创建了可运行的jar此错误，它与openCV本机库路径有关系
使用Eclipse时，我可以使用以下方式设置的路径：
//system.loadlibrary(core.native_library_name(;
但是，在使用Hadoop执行可运行的jar时，它会出现错误。任何可以纠正的人？

您收到的错误消息与无法使用OPENCV的工人有关，因为它未安装在相应的计算机上。因此，该解决方案将在已安装NodeManager组件的集群机上安装OpENCV(将执行任务的组件(。为了能够使用System.loadLibrary()方法加载库，您需要将so文件的位置添加到PATH系统变量。
