Oozie SSH行动问题：

问题：
我们正尝试在我们的特定主机上运行少量命令簇。我们同样选择了SSH Action。一段时间以来，我们一直面临着这个SSH问题。这里真正的问题是什么？请指向我的解决方案。

解决方案
我刚碰到类似的问题。我有一个我可以作为USER运行的例子：

ssh -o PasswordAuthentication = no -o KbdInteractiveDevices = no -o StrictHostKeyChecking = no -o ConnectTimeout = 20 [email protected] mkdir -p oozie-oozi / 0000000-131008185935754-oozie-oozi -W / action1 -ssh /
手动在命令行上运行，但是当通过Oozie以USER身份启动时，它失败了。

在我的情况下，失败的是我在oozie服务器上的USER和远程机器上的USER之间设置了无密码ssh。需要做的是在oozie服务器上的oozie和远程机器上的USER之间设置无密码ssh。换句话说，su在oozie服务器上进行操作并手动运行上述命令。如果失败，它将在Oozie中失败。如果有效，那么它应该在Oozie中工作（假设所有其他都是正确的，比如dir权限等）。

看看你的oozie服务器运行的是什么用户as：

ps -ef | grep oozie
无论用户在远程计算机上需要使用无密码ssh还是USER。

解决方案
I just hit a similar problem. I had a case where I could run as USER:
ssh -o PasswordAuthentication=no -o KbdInteractiveDevices=no -o StrictHostKeyChecking=no -o ConnectTimeout=20 [email protected] mkdir -p oozie-oozi/0000000-131008185935754-oozie-oozi-W/action1--ssh/
by hand on the command line and it worked, but when launched via Oozie as USER it failed.
The reason, in my case, it failed is that I set up passwordless ssh between USER on the oozie server and USER on the remote machine. What one needs to do is set up passwordless ssh between oozie on the oozie server and USER on the remote machine. In other words, su to oozie on the oozie server and run the above command by hand. If it fails, it will fail in Oozie. If it works, then it should work in Oozie (assuming all else is correct, like dir permissions, etc.)
Take a look at what user your oozie server is running as:
ps -ef | grep oozie
Whatever user that is needs passwordless ssh to USER on the remote machine.
