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.....java

一直报错，无论反复建立文件或者脚本多少遍，也无论从新定义workflow多少遍，报错信息始终以下：linux

2.错误缘由　　

在这个问题上纠结了一成天的我都快要怀疑人生了...shell

想过会不会是HUE的忽然失灵，清除浏览器缓存从新登陆试试apache

想过会不会又是脚本编码问题查了一遍都是UTF-8呀......windows

想过会不会是目录权限问题挨个的比对了一遍都同样呀浏览器

........缓存

而后，想了想总共四个脚本其中脚本能够正常执行，可是另外的3个脚本为何就会报错呢！！！app

而后咱们来看一下脚本的隐藏信息工具

经常使用的编辑文件的工具： NotePad++oop

点击下图标记的工具类按钮：【显示全部字符】，咱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

替换后的文件以下：（再从新上传到HUE,执行对应的workflow便可）

调度绿色经过,开开心心！！！
