   ### Search before asking
   
   - [X] I have searched in the [issues](https://github.com/apache/incubator-kyuubi/issues?q=is%3Aissue) and found no similar issues.
   
   
   ### Describe the flaky test
   
   ```
   - all hadoop related environment variables are configured except FLINK_HADOOP_CLASSPATH *** FAILED ***
   ```
   
   The test case(call it T in the following text) was accidentally broken by #2827, but it always passes in CI because due to we split the test cases.
   
   In detail, before #2827, the `kyuubi-server` depends on `kyuubi-flink-engine`, so T always sees the compiled jars of `kyuubi-flink-engine`, and uses `FLINK_HADOOP_CLASSPATH` to detect jar of `kyuubi-flink-engine`.
   
   After #2827, the `kyuubi-server` does not depends on `kyuubi-flink-engine`, and when `FLINK_HADOOP_CLASSPATH` is absent, fallback to detect jar of `kyuubi-flink-engine` by relative path. Then when `FLINK_HADOOP_CLASSPATH` is absent,
   1) if we compile `kyuubi-flink-engine` before `kyuubi-server`, T failed that's the situation of [1].
   2) if we do not compile `kyuubi-flink-engine` before `kyuubi-server`, T passed.
   
   So, T failed does not mean a bug, T should be enhanced or removed.
