Pre-Upgrade Steps for Drill

If you have advanced configurations for Drill, you need to create a backup of storage plugins and configuration files if you made configuration changes that you want to carry over to the next version.

  1. Start the Web Console. The Drill node that you use to access the Web Console must be a node that is currently running the Drillbit process.
  2. Click Storage.
  3. Click Update next to a storage plugin.
  4. Copy the configuration to a text file, and save the file.
  5. Repeat steps 3 and 4 for each storage plugin configuration that you want to save.
  6. Navigate to /opt/mapr/drill/drill-<version>/conf, and copy drill-override.conf and to a location outside of the MapR installation directory
    After upgrading, you can reapply changes to the updated Drill installation using the backup.
