Move Atlas out of migration mode

Once the installation is completed, you must move Atlas out of migration mode.

  • Atlas does not collect metadata from services running on the cluster. The metadata remains in Kafka topics and collected later.

  • Atlas imports metadata when it finds a final transformation file in the location you specified in Confirm the output file location from the step "Click Add Atlas Service."

To move Atlas from migration mode into normal operation:

  1. Open Cloudera Manager to the Atlas service.
  2. Go to the Configuration tab.
  3. Filter the list of properties by typing "Safety" in the filter field.
  4. Remove the migration-specific entries from the Atlas Server Advanced Configuration Snippet (Safety Valve) for conf/atlas-application.properties

    Remove the following properties:

    Atlas.migration.data.filename
Atlas.migration.mode.batch.size
atlas.migration.mode.workers
  5. Reset the Atlas Max Heapsize property back to the default value.
  6. Click Save Changes.
  7. Restart Atlas. Choose Action.
  8. Restart.
