tingxi opened a new issue #5186:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/5186
**Describe the bug**
When we restart the DS server, DS kills all the yarn apps.It happens when
the task contains commands
**To Reproduce**
**Expected behavior**
A clear and concise description of what you expected to happen.
1. Create a DS shell task with the command: yarn application -list
2. Restart the DS server after starting the task
3. Then you will see all the yarn apps will be killed by DS.
**Screenshots**
**Which version of Dolphin Scheduler:**
-[1.3.5]
**Additional context**
**Requirement or improvement**
DS will store the task execution log in the temporary log file, which
contains the yarn app ids , so that DS service can restart the task after it is
restarted.
The point is that DS only performs regular matching on yarn application id,
and kill & restart yarn app ids. **{@link
org.apache.dolphinscheduler.server.utils.ProcessUtils#killYarnJob()}**,that
method will get all the app ids from {@param taskExecutionContext} by {@method
taskExecutionContext.getLogPath()}.
Repair suggestion: add salt value to the yarn app ids in the log, and get
app ids after matching the salt value in **LoggerUtils#getAppIds** method when
restarting.
