I followed the installation instruction on the linkis page, no errors were reported.

Reinstalled linkis version 0.9.2, the original issue was gone. Another one appeared.

What service should be listening on port 9000 ?
How to delete the half-created workflow ? Should I delete some rows in some tables ?
