Description

Phenomenon 

Currently, SSH Action checking operation are as following: 

Firstly, check operation is to check Oozie ppid. When pgid does not exist, check whether there is an error file. If the error file does not exist, Oozie will set action status OK

However, when Oozie pgid is killed externally, this action will be incorrectly determined to be successful.

Solution

In ssh-wrapper.sh, when command execution is OK, Oozie should touch a success empty file like touching error file.
In SshActionExecutor check method, Oozie should add checking the success file existence.
