-----------------------------------------
Summary: Handling of references to non-existing entities in
notifications
Key: ATLAS-3405
URL: https://issues.apache.org/jira/browse/ATLAS-3405
Project: Atlas
Issue Type: New Feature
Components: atlas-core
Affects Versions: 2.0.0
Reporter: Sarath Subramanian
Assignee: Sarath Subramanian
Fix For: 2.1.0
Hook notifications containing references to non-existing entities are dropped
by Atlas server, with the following error:
AtlasObjectId\{guid='null', typeName='hive_db',
uniqueAttributes={qualifiedName:db1@prod}} is not found
Instead of dropping such notifications, it will help to create an entity for
the reference, and complete processing of the notifications. Such entities will
only have its unique-attribute populated, however will capture the lineage and
other relationships. When Atlas receives details of the entity in a subsequent
notification, Atlas will have rest of the attributes populated as well.
