Description

1. In source cluster , updated relationshipDef "hive_table_db" propagateTags to "ONE_TO_TWO" from NONE and exported.
   2.In export zip , atlas-typesdef.json has "ONE_TO_TWO" propagateTags value for "hive_table_db" .
   3. But in the import cluster, propagateTags value for hive_table_db is NONE still. In the import options , provided updateTypeDefinition to True too.

Steps to Duplicate

1. In source cluster edit ./atlas-server/server/models/1000-Hadoop/1030-hive_model.json
2. Go to relationshipDefs and update hive_table_db to the following definition:

        {
            "name": "hive_table_db",
            "serviceType": "hive",
            "typeVersion": "1.2",
            "relationshipCategory": "AGGREGATION",
            "relationshipLabel": "__hive_table.db",
            "endDef1": {
                "type": "hive_table",
                "name": "db",
                "isContainer": false,
                "cardinality": "SINGLE",
                "isLegacyAttribute": true
            },
            "endDef2": {
                "type": "hive_db",
                "name": "tables",
                "isContainer": true,
                "cardinality": "SET"
            },
            "propagateTags": "ONE_TO_TWO"
        }

Note that propagateTags is changed from NONE to ONE_TO_TWO.

3. Perform export using this request:

{    
  "itemsToExport": [
  {
    "typeName": "hive_db",
    "uniqueAttributes": { "qualifiedName": "smalldb16@cl1" }    
    }], 
 "options": {"fetchType": "full" }
}

4. Perform an import on target cluster with no request parameters.

5. Use this REST call to fetch typesDef:

http://localhost:21000/api/atlas/v2/types/typedefs

Note the definition of hive_table_db.

 

Expected results: Import updates hive_table_db on imported cluster_._

Observed results: Relationship definition for hive_table_db on target cluster remains unchanged.
