xxjingcd opened a new issue #5132:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/5132


   
   **Describe the bug**
   
   When an exception occurs in the taskExecuteThread, task will  be called the  
`cancelApplication()` method to stop the task immediately。Howerver，the task 
whose` cancelApplication()` method  base on the 
`AbstractCommandExecutor.cancelApplication()` cannot be killed 
immediately,because `AbstractCommandExecutor.cancelApplication()` would not 
call `hardKill()` method when soft kill process fail;
   
   **To Reproduce**
   
   
   **Expected behavior**
   In order to make the error task stop immediately ，It should call the 
`hardKill()` method when soft kill process fails；
   
   **Screenshots**

   **Which version of Dolphin Scheduler:**
    -[dev]
   
   **Additional context**
   It is a very simple Bug, the `softKill()` method returns the opposite state, 
so just modify the return value can fix this bug. I will fix this Bug.
    
   **Requirement or improvement**
