Neither of them. Our ranger is in the container environment。Based on the Ranger
image, every container instance invokes the setup.sh script before launching
the RangerAdmin service.

> Project: Ranger
> Issue Type: Improvement
> Components: admin
> Affects Versions: 1.2.0, 2.2.0
> Reporter: Binhua Hu
> Priority: Major
> Attachments: ranger database volume.png, ranger log.png
>
>
> 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!
