sychen 4bf17a25ed [KYUUBI #1473] Exit gracefully when engine idle ... ### _Why are the changes needed?_ https://github.com/apache/incubator-kyuubi/issues/1473 It is not graceful to exit when engine is idle, which may cause AM to try again. The current workaround is to configure `spark.yarn.maxAppAttempts`. ``` yarn.ApplicationMaster: Final app status: FAILED, exitCode: 16, (reason: Shutdown hook called before final status was reported.) ``` ### _How was this patch tested?_ - [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible - [x] Add screenshots for manual tests if appropriate - [ ] [Run test](https://kyuubi.readthedocs.io/en/latest/develop_tools/testing.html#running-tests) locally before make a pull request Closes #1474 from cxzl25/KYUUBI-1473.
