hadoop - 无法在 oozie 中运行 shell(错误=2，没有那个文件或目录)

Question

我在 ambari-views ui 中为我的工作流程中的 oozie 和 sample.sh 文件创建工作流程运行后我有一个错误。当我将 shell 主体更改为简单命令时，例如 echo 1 此错误没有出现请多多指教

我遇到了同样的问题，但就我而言，根本原因是 shell 脚本的 CRLF 行分隔符 (\r\n)。

当我将 shell 脚本的行分隔符更改为 LF (\n) 时，此问题得到解决。

注意:在 Windows 中使用默认设置的 IntelliJ 时，CRLF(\r\n) 将是默认的行分隔符
