Michael Smedberg commented on ATLAS-2498:
-----------------------------------------

FWIW, here's a `git describe` of a change I made to my local Atlas which allowed me to use hard-delete on entities that had already been soft-deleted: [^hard_delete_soft_deleted_items.diff]

> Hello,
> Since the documentation on this feature not clear, could you please answer or confirm the following:
>  # When an entity is deleted, its status goes to "DELETED", this is a soft delete.
>  # Does Atlas version 0.8.0 support hard deletes (HDP 2.6.4 ships with 0.8.0)?
>  # Is the atlas.DeleteHandler.impl configuration key supported in this version?
>  # Is it possible to delete a "DELETED" entity?
> I am asking this because I am stuck in the following scenario:
>  * Create a new ENTITY type named "custom_type"
>  * Create an entity of that type "entity_1_of_custom_type", its status is "ACTIVE"
>  * Delete the entity "entity_1_of_custom_type", its status is "DELETED"
>  * Delete the ENTITY type named "custom_type"
>  * I get an error: \{"errorCode":"ATLAS-409-00-002","errorMessage":"Given type custom_type has references"}
> How is it possible in this case to cleanup both the DELETED entity and the unused type "custom_type"?
> Thanks!
