MapReduce 未运行。 /bin/bash: /bin/java: 没有这样的文件或目录
我收到以下错误。
[2022-03-01 20:03:49.581]Container exited with a non-zero exit code 127. Error file: prelaunch.err.
Last 4096 bytes of prelaunch.err :
Last 4096 bytes of stderr :
/bin/bash: /bin/java: No such file or directory
我已经在 hadoop-env.sh 中设置了 JAVA_HOME。我在 MacOS 12.1 上运行，因此无法使用符号链接。
hadoop-env.sh配置：
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-11.0.13.jdk/Contents/Home
重新安装Hadoop两次。
任何意见都会受到赞赏。
Hadoop版本：3.3.1（hadoop-config.sh即可）
I am getting the following error.

I have set up my JAVA_HOME in the hadoop-env.sh. I am running on MacOS 12.1 so symlink is not possible.
hadoop-env.sh configuration:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-11.0.13.jdk/Contents/Home
Reinstalled Hadoop twice.
Any input is appreciated.
Hadoop version: 3.3.1 (hadoop-config.sh is fine)

我已经卸载了Hadoop的brew安装，直接从apache网站安装。现在正在工作。
有趣的是，我发现 sbin 文件夹中的所有脚本都有 JAVA_HOME 预定义的不同路径“/opt/hombrew/opt”，而不是我的 Java（我从网络安装而不是自制程序）所在的路径。我猜想 Hadoop 的自制版本将所有 Java 版本预设为已安装的 java 的软链接所在的位置。
我再次安装了hadoop的自制版本，我可以看到当前正在推送3.3.2。
start-all.sh 脚本如下：
从 Apache 网站下载的 Hadoop 的文件夹分布与从 Homebrew 下载的 Hadoop 的文件夹分布有点不同。
I have uninstalled the brew installation of Hadoop and installed it directly from the apache website. It is working now.
Interestingly I found all the scripts in sbin folder have JAVA_HOME predefined different path '/opt/hombrew/opt' than what my Java (I installed from the web instead of homebrew) is at. I guess homebrew version of Hadoop presets all the Java versions to where a softlink of the java installed is present.
I have again installed homebrew variant of hadoop, I can see that 3.3.2 is being pushed currently.
The start-all.sh script is as such:
The folder distribution of Hadoop downloaded from the Apache website and from Homebrew is a bit different.
