我正在使用 Mac OSX El-Capitan，并且是 hadoop 的新手。安装后我收到此警告:
WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

我该如何解决？
最佳答案
您必须自己编译 hadoop 才能解决此问题。
问题不是所有的hadoop都是用java写的。 hadoop 附带了几个 native 库，它们依赖于操作系统中的其他库。某些依赖项未得到满足，因为您下载的 hadoop 是在不同的系统上构建的。
