@mrtisttt `kyuubi.engine.user` is supposed to be a server level parameter. Besides, your comment mentioned a situation I did not consider before: 1. `kyuubi.engine.user` is not set 2. User `Tom` launched a SparkSQLEngine 3. `kyuubi.engine.user` is set to `kyuubi` and kyuubi server is restarted 4. User `Tom` connects to kyuubi server again 5. an `EngineRef` with `appUser=kyuubi` and `engineSpaceUser=Tom` is created 6. `HadoopCredentialsManager` will send credentials of `kyuubi` to SparkSQLEngine using credentials of `Tom` The last step changes the `UserGroupInformation` of SparkSQLEngine from `Tom` to `kyuubi`. It will probably result in many unexpected behavior. -- This is an automated message from the Apache Git Service.
