【中文标题】线程“main”java.sql.SQLException 中的异常：运行 spark-submit 时没有合适的驱动程序

【英文标题】：Exception in thread "main" java.sql.SQLException: No suitable driver while running spark-submit

【发布时间】：2018-07-20 06:55:38

【问题描述】：

Spark 版本：2.3.0

我正在使用 --jars 选项运行 spark-submit 命令。

我已经在命令中提供了ojdbc6.jar，如下图。

命令

./spark-submit --class com.sample.ABC --jars /scratch/user/abc/drools-jars/ojdbc6.jar --master spark://IP:Port "/scratch/user/abc/POC jar/ABC-0.0.1-SNAPSHOT.jar"

我仍然遇到异常：

【参考方案1】：

在命令中添加--driver-class-path，如下所示：

./spark-submit --class com.sample.ABC --jars /scratch/user/abc/drools-jars/ojdbc6.jar `--driver-class-path /scratch/user/abc/drools-jars/ojdbc6.jar --master spark://IP:Port "/scratch/user/abc/POC jar/ABC-0.0.1-SNAPSHOT.jar"

这解决了问题。
