Hi @Swarvenstein, I notice the engine log contains the following message ``` SparkTBinaryFrontendService: Received request of closing SessionHandle [0d8be737-c71d-4870-954b-831835390f09] ... SparkSQLSessionManager: SessionHandle [0d8be737-c71d-4870-954b-831835390f09] is closed, current opening sessions 0 ... SparkSQLSessionManager: Session stopped due to shared level is Connection. ``` It indicates that you are using the CONNECTION engine share level, which means every connection(session) will create a new spark application, and once the connection(session) is closed, the engine will self-terminate immediately to save resources. If you want to share the engine(spark application) across sessions(connections), please set `kyuubi.engine.share.level` to another options like 'USER' Ref: https://kyuubi.readthedocs.io/en/master/deployment/engine_share_level.html -- This is an automated message from the Apache Git Service.
