> URL: https://issues.apache.org/jira/browse/ATLAS-3316
> Project: Atlas
> Issue Type: Bug
> Reporter: Nixon Rodrigues
> Assignee: Mandar Ambawane
> Priority: Major

>
>
> In EntityGraphMapper.java
> {code:java}
> public AtlasVertex getResolvedEntityVertex(AtlasObjectId objId) {
> AtlasVertex vertex = resolvedIdsByUniqAttribs.get(objId);
> {code}
>
> getResolvedEntityVertex method returns null if AtlasObjectId has AtlasRelatedObjectId.
>
> Even if the AtlasObjectId and AtlasRelatedObjectId refer to the same entity (conceptually the same), they will have different hashcode, the server cannot use hashcode of AtlasRelatedObjectId to find AtlasObjectId.
>
> The fix is to create new AtlasObjectId from AtlasRelatedObjectId values and use that for lookup
