Place Atlas in migration mode

Before starting the upgrade from HDP 2.6.5.x to HDP intermediate bits, within Atlas you must set the atlas.migration.data.filename property to point to a non-existent directory.

It is mandatory to ensure that the pre-upgrade checks within Ambari are completed. After you upgrade to HDP intermediate bits, the migration is prevented from starting. This property will be set to the correct path. Configure the atlas.migration.data.filename property.
  1. In Ambari, select Services > Atlas > Configs > Advanced > Custom application-properties.
  2. Click Add Property, and add the atlas.migration.data.filename property.

    Example: atlas.migration.data.filename=/tmp/non-existent-path
