-->
According to this PR https://github.com/apache/spark/pull/37880 when user spark submit without `--deploy-mode XXX` or `–conf spark.submit.deployMode=XXXX`, may face NPE with this code.
https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#164
```scala
args.deployMode.equals("client") &&
```
Of course, submit without `deployMode` is not allowed and will throw an exception and terminate the application, but we should leave it to the later logic to give the appropriate hint.

@shrprasa Thanks for reminder
I saw this default value, you can do local test with writing following code
The default value client you mean, will be set in `prepareSubmitEnvironment` function, which be called after check
```
args.deployMode.equals("client") &&
```

```

Please use the jira-style prefix [SPARK-42785], not a GitHub issue-like one [SPARK #42785] like apache/kyuubi.

@zwangsheng args.master.startsWith("k8s") will also throw NPE if job is submitted without master arg?
