Are you installing the fresh setup(cluster) or upgrading the ranger version?

> In the docker container or distributed nodes, the initialization script(setup.sh) may be executed many times. Ranger controls the initialization process through database table（x_db_version_h）. However, when the number of database connections is too large or the network is abnormal, the initialization script will judge abnormally, the script will trigger reconstruction, and the data will be lost.So is it reasonable to drop tables in script(ranger_core_db_XX.sql).
> The initialization log is as follows，
> !ranger log.png!
> The data volume in the Ranger database is as follows，
> !ranger database volume.png|width=957,height=360!
