> Can you give an example?
In current UpgradeDolphinScheduler code：
```JAVA
@Override
public void run(String... args) throws Exception {
if (dolphinSchedulerManager.schemaIsInitialized()) {
dolphinSchedulerManager.upgradeDolphinScheduler();
logger.info("upgrade DolphinScheduler finished");
} else {
dolphinSchedulerManager.initDolphinScheduler();
logger.info("init DolphinScheduler finished");
}
}
```
it has been judged whether the schema has been initialized. If not, it will
be initialized, but it will not upgrade after that. I don't think this is
reasonable.
The initDolphinScheduler function only update the schema to version
3.0.0（not the latest version），so i have to run this function again to upgrade
the schema.
I don't understand why not init&update to the latest version all at once？
