为了使用hdfs服务，我正在尝试安装hadoop。我是在windows（不是vm）上的ubuntu上的bash中完成的：

我遵循的教程是这样的（与大多数hadoop安装教程非常相似）：

所以一切都很顺利，直到我试着 start-dfs.sh 但我得到了以下错误信息：

17/12/12 22:19:06 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

我确保 ssh localhost 成功了，我还允许使用hadoop文件夹 chmod -R 755 hadoop/ 并将root权限授予为执行hadoop实现而创建的用户。
如果你有任何线索或解决这个问题，这将是惊人的。
