Review comment:
Hi, @vanzin . Can we check the actual pattern you introduced here? Maybe, we
can use `.startWith` and `endWith`.
```
val shorterServiceName = s"spark-$randomServiceId$DRIVER_SVC_POSTFIX"
```
Negative assertions(at 106 and 109) looks insufficient to check the new
logic. If something happens on the patterns, this test doesn't catch the change
at all. Previously, we check the name pattern
[exactly](https://github.com/apache/spark/pull/23805/files#diff-0d7a047564dda7b7bdbb656040c0600bL110).
