Ensure HBase populates pre-existing object storage data

Cloudera Operational Database (COD) databases store data in cloud storage. The location of the data is stored in cloud storage is defined by the data access cloud storage location in the CDP environment and the COD database name .

When a COD database is dropped, any data stored in the cloud storage is not dropped. You must delete the data separately if you no longer need it. If a COD database is created against a cloud storage location which already contains COD data from a previous instance of COD, COD will automatically re-create the tables with the corresponding data in the new COD instance. Multiple COD databases must not refer to the same cloud storage location as this will cause data loss and data corruption.

If a COD database is created using the same name against a cloud data access storage location, which already contains COD data from a previous instance of COD, COD will automatically re-create the tables with the corresponding data in the new COD instance.
