idea连接hbase时报错Exception in thread "main" java.io.IOException: java.lang.reflect.InvocationTargetException
详细错误如下：

上官网查看hbase与java哪些版本兼容：
再查看自己用的java版本：
竟然是11！
改为1.8即可，需要修改的地方有3个！！
一个上面已经提到了，下面这个位于：“File” -->“Project Structure”或 文件 --> 项目结构
敲黑板！！特别注意这里别忘改了
“Settings”-->“Bulid, Execution,Deployment”-->“Java Compiler”或 设置 -->构建、执行、部署 --> java编译器中的Target bytecode version设为本地Java版本
修改好后，执行成功：
