我在跟踪https://amodernstory.com/2014/09/23/installing-hadoop-on-mac-osx-yosemite/ 在mac上安装hadoop以执行本地小任务。
当hs启动/hs停止时，获取“ WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable "
尝试了以下链接中的选项，为lib/native重命名文件夹/路径。已重命名 libexec/ 至 lib/ 但是libexec应该正确的脚本错误。hadoop“无法为您的平台加载本机hadoop库”警告
但是，在hadoop 3.0.0中，结构如下：

username-local:hadoop me$ pwd
/usr/local/Cellar/hadoop

username-local:hadoop me$ ls
3.0.0   hdfs

username-local:hadoop me$ cd 3.0.0/
username-local:3.0.0 me$ ls
INSTALL_RECEIPT.json    NOTICE.txt      bin         sbin
LICENSE.txt     README.txt      libexec

username-local:3.0.0 me$ cd libexec/
username-local:libexec me$ ls
bin etc libexec logs    sbin    share

username-local:libexec me$ cd libexec/

有什么想法吗？谢谢您。
