### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### 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 bug  用java jdbc的方式连接 kyuubi ，提交一条sql ， spark 会生成两个集群。一个是show databases，另外一个是 show databases + 提交的sql 。   这种在connection的模式下， 我的理解，show tables是engine_initializing_queries 在SparkSqlEngine 135 行执行，后面都是返回这个session ，为什么会产生两个spark 作业了，向k8s申请两次不同的资源了。 ### Affects Version(s) 1.5.1 ### Kyuubi Server Log Output ```logtalk 没有报错 ``` ### Kyuubi Engine Log Output ```logtalk 没有报错 ``` ### Kyuubi Server Configurations ```yaml kyuubi.session.engine.initialize.timeout 600000 # 约定Driver闲置了多长时间以后也释放 kyuubi.session.engine.idle.timeout 300000 kyuubi.engine.share.level CONNECTION kyuubi.engine.connection.url.use.hostname false kyuubi.session.idle.timeout 1800000 ``` ### Kyuubi Engine Configurations ```yaml 没有配置 ``` ### Additional context 无 ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
