Which branch

[shaobo99]

1.3.0-release

[xingchun-chen]

1. I did not reproduce the problem, please confirm that the code is 1.3.0-release instead of dev, because the dev code may have this problem.
2. You can check the worker log, and confirm that the dataX environment variable is configured correctly in conf/env/dolphinscheduler_env.sh, and the dataX driver is added under lib

I would close this issue since no response from user and @xingchun-chen can not reproduce, you could reopen it if you have further information
