Current limitations

Because this feature is in tech-preview, there are a number of limitations and caveats.

  • There is no automated opt-in to this feature for already existing databases. Deploy a new database using the above directions.
  • Previously existing COD databases which are upgraded to Cloudera Runtime 7.2.14 will not use this storefile tracking feature. These databases will continue to use HBOSS to safely interact with S3.
  • User applications which rely on HBase or Phoenix bulk loading may experience some issues while this feature is in tech-preview. Please contact Cloudera if you are reliant on bulk loading and want to leverage this feature.
  • Restoring HBase snapshots (clone_snapshot and restore_snapshot) has been observed to be unstable at the 1TB scale. You can contact Cloudera for assistance on this topic.
