1.问题描述
Fayson前面的一篇文章讲过《如何在Hue中创建Ssh的Oozie工作流》。但当重定向输出日志时，会出现异常。
Ssh Action的Oozie工作流创建如下：
运行异常日志如下,提示：代码块部分可以左右滑动查看噢

通过上述方式创建Ssh Action工作流主要是由于”>> /tmp/out.log”引起，如果只是执行“ls /”，Ssh Action是可以正常运行成功的，可以通过如下方式实现：
1.在要执行命令的服务上创建一个shell脚本，脚本内容如下：
[fayson@ip-172-31-22-86 ~]$ vim ssh-action.sh
#!/bin/bash
ls / >> /tmp/out.log
2.设置ssh-action.sh执行权限，只有fayson用户可以执行该脚本
[fayson@ip-172-31-22-86 ~]$ chmod 744 ssh-action.sh
3.创建Ssh Action工作流
在Ssh command中配置对应服务的Shell脚本”/home/fayson/ssh-action.sh”
4.提交Oozie工作流，执行成功
5.查看服务/tmp/out.log文件
3.总结
- 在使用Hue创建Ssh Action的Oozie工作流直接在Ssh command中输入命令重定向会导致运行失败，可以使用在执行命令的目标服务使用Shell脚本的方式实现该功能。
这里Fayson在做测试的时候发现，在命令行前面添加”;”也可以实现重定向输出日志，实现如下（这种实现方式比较诡异，仅供参考）：
为天地立心，为生民立命，为往圣继绝学，为万世开太平。
