Apache Atlas many to many relationship between entities
Hi,
I'm trying to create many to many relationships between two entities, but
I'm getting the below error errorMessage': 'Relationship end is invalid.
> *Expected application but is NULL *
this is the relationship def that I created
{ "name": "subscribe", "typeName": "subscribe", "description": "Client
provided by the application", "category": "RELATIONSHIP", "typeVersion":
"1.0", "relationshipCategory": "ASSOCIATION", "propagateTags": "NONE",
"endDef1": { "name": "application", "type": "client", "cardinality": "SET",
"isContainer": false, "isLegacyAttribute": false }, "endDef2": { "name":
"client", "type": "application", "cardinality": "SET", "isContainer":
false, "isLegacyAttribute": false } }
and this is the json object that i used to create entity,
{ "entity": { "typeName": "service", "attributes": attributes,
"relationshipAttributes": { "application": {"typeName": "application",
"uniqueAttributes": {"id": application_id}} } } }
If anyone has experience with many to many relationships in apache atlas,
please let me know what Im doing wrong.
Thanks

Randheer,
Looking at the definition of relationship 'subscribe', it requires following types of entities at its ends:
- end1: client
- end2: application
However, the entity you are trying to create (of type 'service'), requires relationship definition with following ends:
- end1: service
- end2: application
Either the relationship definition, or type of entity you are createing needs update to be in sync.
Hope this helps.
