尝试运行插入查询。日志中出现错误，

[2023-03-11 03:39:10.914]容器以非零退出代码 127 退出。错误文件：prelaunch.err。

prelaunch.err 的最后 4096 字节：

stderr 的最后 4096 字节：

/bin/bash: /Library/Internet: 没有这样的文件或目录

Answer 1

HDFS 不包含 /Library 文件夹，macOS 机器也不包含。

更改 Hive 设置或表定义以不引用 Mac 特定文件路径

Answer 2

正如我在评论中所写，我认为问题是由 java 所在路径中存在的文件夹名称（即

Internet Plug-Ins

）中的空格引起的。

为了避免这种情况，我按照这个guide卸载Java，然后使用Homebrew安装了OpenJDK（您也可以使用SDKMAN或asdf-java，而不是按照@OneCricketeer的建议从Oracle下载Java）

Answer 3

我也遇到了类似的问题，设置为 /Library/internet Plug-Ins/.... 的 $JAVA_HOME 变量应该替换为 Library/Java/JavaVirtualMachines/{jdk-version}.jdk/Contents/Home 和更新 hadoop-env.sh 上的 $JAVA_HOME 记录以反映新的 $JAVA_HOME 路径，然后停止并重新启动 hadoop，它现在应该可以正常工作了。
