### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened Sorry for mark the option 'No similar issues found' since I found the similar issues #13602 #13119 #13085 but not found any good solution to salve it. I'm using version 3.0.0 When multiple sql-tasks with connecting hiveserver2 and scheduled at the same time, it seems that the Hive session will only be created once. which means that the first task can obtain the Hive connection, while other tasks will report the null pointer exception due to not obtaining the connection as follows.   ### What you expected to happen  I execute the same sql-task several times, only the first one SUCCESS. Total number of hive sessions only increase once. I tried to change Hikari pool profile on work-server application.yaml but seams doesn't work. ### How to reproduce just manually executing the same sql-task several times and make sure each sql task runtime will be longer than 30s. ### Anything else It happens every time. Due to some reasons, i can't switch the version immediately. I would like to know if there is a fix for this issue in version 3.2.x or later, which was achieved by canceling hive using the hikari pool? Looking forward to a reply.
