Hi, My team is currently using version 0.8.1-rc1 and can't seem to hard delete entities or update lineage.
1. Hard deleting entities Based on this ticket: https://issues.apache.org/jira/browse/ATLAS-541, it seems like hard deletes should be possible. We uncommented and set `atlas.DeleteHandler.impl` to `org.apache.atlas.repository.graph.HardDeleteHandler` in `atlas-application.properties`, but after making a DELETE request on an entity, we can still see it in the UI (marked as deleted). What is the correct way to hard delete entities in Altas? 2. Updating lineage Based on this thread: https://community.hortonworks.com/questions/ 53470/how-to-delete-lineage-metadata-in-apache-atlas.html, it looks like the way to update lineage is to re-POST a Process entity with the `inputs` and `outputs` attributes updated to reflect the new lineage. However, it looks like updates to these attributes can only be _additive_. POST'ing empty `inputs` and `outputs` arrays have no effect. What's the correct way to delete edges in a lineage graph? Great work on the tool so far! -marc
