----------------------------
Assignee: Le Ma
> Namespace entity relationship-attribute names to avoid conflict with entity
> attributes
> --------------------------------------------------------------------------------------
>
> Key: ATLAS-2928
> URL: https://issues.apache.org/jira/browse/ATLAS-2928
> Project: Atlas
> Issue Type: Bug
> Components: atlas-core
> Affects Versions: 1.0.0, 1.1.0
> Reporter: Madhan Neethiraj
> Assignee: Le Ma
> Priority: Critical
> Fix For: 1.2.0, 2.0.0
>
>
> Apache Atlas 1.0 introduced relationships as first-class types. A
> relationship effectively 'injects' an attribute on the entities at each end.
> For example, assignment of a glossary term to an entity is captured by
> relationship AtlasGlossarySemanticAssignment (in
> 0000-Area0/0011-glossary_model.json). This relationship adds following
> attributes:
> - Referceable.meanings: set<AtlasGlossaryTerm>
> - AtlasGlossaryTerm.assignedEntities: set<Referenceable>
> This works fine as long as the entity-types involved in the relationship, or
> their sub-types don't have an attribute with the same name as the attribute
> injected by the relationships. Once such instance was reported by [~bolke],
> about relationship attribute DataSet.schema introduced by
> avro_schema_associatedEntities - which conflicts with spark_table.schema,
> since spark_table type is a sub-type of DataSet.
> Such name conflicts can be avoided by prefixing relationship-attribute names
> with a prefix like "r:".
