      Description

      Attached a python script to reproduce this issue. It creates and deletes 10 column masking policies repeatedly. Run it and refresh column masking policies in Hive service in Ranger Admin UI. Some policies won't be deleted after several rounds.

      Delete them manually in Ranger Admin UI will get an error as org.apache.ranger.plugin.model.RangerPolicy :Data Not Found for given Id

      Can't neither view them nor edit them. The web UI will hang. Ranger logs reveal the same error:
