dolphinscheduler版本：apache-dolphinscheduler-2.0.3-bin
sqoop版本：1.4.7
在任务调度中不断的报错说没有驱动，但是我查看了 dolphinscheduler 的 lib 和 sqoop 的 lib 目录，发现都有 mysql 的驱动，而且版本符合安装的版本。
后来发现是 sqoop 的参数没有配置全
需要在 dolphinscheduler 的配置页面添加如下参数：
–driver com.mysql.jdbc.Driver

找不到 sqoop 命令：
- SQOOP_HOME路径，环境变量要配置，dolphinscheduler 的 /opt/module/ds/conf/env/dolphinscheduler_env.sh 中也要配置每个服务节点都要有 sqoop
