Ensure HBase populates pre-existing object storage data
Cloudera Operational Database 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 Cloudera environment and the Cloudera Operational Database database name .
When a Cloudera Operational Database 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 Cloudera Operational Database database is created against a cloud storage location which already contains Cloudera Operational Database data from a previous instance of Cloudera Operational Database, Cloudera Operational Database will automatically re-create the tables with the corresponding data in the new Cloudera Operational Database instance. Multiple Cloudera Operational Database databases must not refer to the same cloud storage location as this will cause data loss and data corruption.
If a Cloudera Operational Database database is created using the same name against a cloud data access storage location, which already contains Cloudera Operational Database data from a previous instance of Cloudera Operational Database, Cloudera Operational Database will automatically re-create the tables with the corresponding data in the new Cloudera Operational Database instance.
