Disable Operational Database powered by Apache Accumulo's use of HDFS trash

Using Cloudera Manager, you can configure Operational Database powered by Apache Accumulo (OpDB) to skip the saving of the HDFS trash.

In some deployments, changing the system-wide retention period for HDFS trash may not be an option. If that is the case, you can disable Accumulo’s use of the HDFS trash entirely. If you do so, any deletions through the Accumulo APIs are unrecoverable.

  1. In Cloudera Manager, select the Accumulo on CDP service.
  2. Click Configuration.
  3. Search for accumulo.properties.
  4. Find Tablet Server Advanced Configuration Snippet (Safety Valve) for accumulo.properties property.
  5. Set the following: 
    gc.trash.ignore=true
  6. Save your changes.
  7. Click Restart Stale Services.
