I can kill the task, after install the `pstree` on my environment.
And the task can be killed successfully.
But there is still an error, that I don't have permission to kill the parent process, but I can kill the subprocess, so the task is still be killed.
```

I also have the problem, but my problem is due to no permission.
When I run a shell task by a specific tenant.
```
[INFO] 2021-04-03 13:17:27.347 - [taskAppId=TASK-4-62-65]:[327] - task run command:
sudo -u ruanwenjun sh /tmp/dolphinscheduler/exec/process/1/4/62/65/4_62_65.command
[INFO] 2021-04-03 13:17:27.348 - [taskAppId=TASK-4-62-65]:[202] - process start, process id is: 7191
```
And I find that the task is running by root.
And when I stop the task, it tells me that I don't have permission.
```java
[INFO] 2021-04-03 13:17:38.941 org.apache.dolphinscheduler.server.worker.processor.TaskKillProcessor:[95] - received kill command : TaskKillRequestCommand{taskInstanceId=65}
[INFO] 2021-04-03 13:17:38.941 org.apache.dolphinscheduler.server.worker.processor.TaskKillProcessor:[131] - process id:7191, cmd:sudo -u ruanwenjun kill -9 7191
[ERROR] 2021-04-03 13:17:38.979 org.apache.dolphinscheduler.server.worker.processor.TaskKillProcessor:[137] - kill task error
org.apache.dolphinscheduler.common.shell.AbstractShell$ExitCodeException: kill: 7191: Operation not permitted
```
So my task can run successful, but can not stop.
