HUE Oozie : error=2, No such file or directory采坑记录

HUE Oozie : error=2, No such file or directory采坑记录

1.错误详情

一直都是同一种方式在hue上定义workflow,不知为啥 今天定义的就是不行.....

一直报错，不管反复创建文件或者脚本多少遍，也不管重新定义workflow多少遍，报错信息始终如下：

2.错误原因　　

在这个问题上纠结了一整天的我都快要怀疑人生了...

想过会不会是HUE的突然失灵，清除浏览器缓存 重新登录试试

想过会不会又是脚本编码问题 查了一遍都是UTF-8呀......

想过会不会是目录权限问题 挨个的比对了一遍 都一样呀

........

然后，想了想 总共四个脚本 其中脚本可以正常执行，但是另外的3个脚本为什么就会报错呢！！！

然后 我们来看一下脚本的隐藏信息

常用的编辑文件的工具： NotePad++

点击下图标记的工具类按钮：【显示所有字符】，我们就会发现这里的换行符 是  windows的换行符 \r\n（CR LF） ,linux上识别不了 (llinux识别的是  \n (LF))

3.解决方法

替换windows换行符(\r\n)\为linux的换行符 (\r)

4.解决效果

替换后的文件如下：（再重新上传到HUE,执行对应的workflow即可）

调度绿色通过,开开心心！！！
