dolphinscheduler版本2.0.0
測試步驟：
1.新建數據源測試成功
2.新建工作流執行失敗日誌（從日誌看沒有看錯什麼異常）

3.去對應的work節點查看日誌，具體日誌路徑以爲work的log配置文件爲準:/var/log/udp/1.0.0.0/dolphinscheduler

... 16 common frames omitted看到具體的異常日誌大概知道原因了，需要將相關的依賴上傳到work節點對應的lib目錄/srv/udp/1.0.0.0/dolphinscheduler/lib/plugin/task/sql
4.clickhouse的依賴很多將所有的依賴打包輸出
4.1新建一個maven項目添加clickhouse依賴
4.2執行命令mvn dependency:copy-dependencies -DoutputDirectory=C:\\my\\out
4.3.將依賴上傳並且授權
5.重啓work節點搞定！！！
