我启动kyuubi（基于spark）

bin/beeline -u 'jdbc:hive2://hadoop102:10009/'

**原因：这个报错，是因为你spark没找到这个驱动。**  
解决思路：一般这种框架，在启动的时候都会去加载相应的jar包和配置文件，比如hadoop、hive、spark、zookeeper等等，他们默认加载的jar包都会有一个稍微固定的文件夹的，你可以去他们的安装路径里面找一下，我相信你能找到的。操作办法：你需要把hive里的这个mysql驱动，拷贝到spark默认加载的jar包路径里去，再重启一下应该就可以解决了。

cp mysql-connector-java-5.1.27-bin.jar /opt/module/test_del/spark-3.3.2-bin-hadoop3/jars/
