The JDBC engine has been compiled and installed by itself. After debugging the JDBC engine code, I found that this is a program problem.

"wds.linkis.jdbc.auth.type" must be configured during JDBC engine execution, but this configuration item is not available on the "参数配置" page. The best solution is to add this item to the page and add the default value of "USERNAME". At present, the default value has been considered in the code, but the value of "null" is not considered. The specific question points to line 223 of "src/main/java/org/apache/linkis/manager/engineplugin/jdbc/ConnectionManager.java"。

The jdbc engine is not in the installation package by default. Make sure you compile and add it manually. For details, see
