hadoop - "no such file or directory"oozie 错误

Question

我尝试学习 Oozie，我想做一个非常简单的工作流程。为此，我使用 HUE 创建了第一个 oozie 工作流。

我的第一个工作流程是执行一个 shell 命令文件“testhbase.sh”，其中包含:

#!/bin/sh
echo -e "scan 'hbasedepartementcap' " | hbase shell -n

当我试图将它放入 Oozie 的 shell 图标中时，在执行时我得到:没有这样的文件或目录 ...

我怎么知道要在 oozie 中设置什么参数!!？？？

当您执行 oozie 操作时，所有应用程序(bash 脚本、jar、hql hive 等)都必须存在于 HDFS 路径上，而不是 Linux 文件系统上。
