jywjyw opened a new issue #1193:
URL: https://github.com/apache/incubator-linkis/issues/1193
**bug描述**
非hadoop环境下，无法正常启动，提示获取hive驱动名称时有空指针异常
**重现方式**
版本：1.0.1~1.0.2
我按照《快速部署Linkis1.0.md》的“不依赖HDFS的基础配置修改”介绍的方式进行部署，
运行sbin/linkis-start-all.sh后，在启动linkis-ps-publicservice服务时报错了，
从日志中发现，从配置文件中读取hive数据库连接地址后进行解析时报如下错误：
```
Caused by: java.lang.NullPointerException
at
com.alibaba.druid.util.JdbcUtils.getDriverClassName(JdbcUtils.java:341)
~[druid-0.2.9.jar:0.2.9]
```
实际上我没有hadoop环境，也没有配置hive地址
