hadoop - 如何修复 Hadoop3.1.2 “WARN util.NativeCodeLoader”

Question

我在我的 Mac 上安装了 hadoop，并尝试使用 start-dfs.sh 启动它。但是，我不断收到警告消息：WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... 在适用的情况下使用内置 java 类。关于修改哪些文件有什么建议吗？

Ms-MacBook-Pro% ./start-dfs.sh
Starting namenodes on [localhost]
Starting datanodes
localhost: datanode is running as process 48267.  Stop it first.
Starting secondary namenodes [Ms-MacBook-Pro.local]
Ms-MacBook-Pro.local: secondarynamenode is running as process 48390.  Stop it first.
