I have a list of Classifications & Sub-classifications in Apache Atlas. Want to delete them & create a new list. All the other classifications are getting deleted but one of them with name "PII" giving following error when we select Delete Classification.

enter image description here

Error: Given type PII has references

When we do a search via Rest API using below URL: http://ip.of.atlas:21000/api/atlas/v2/search/basic?classification=PII

Following Result comes:

{
    "queryType": "BASIC",
    "searchParameters": {
        "classification": "PII",
        "excludeDeletedEntities": false,
        "includeClassificationAttributes": false,
        "includeSubTypes": true,
        "includeSubClassifications": true,
        "limit": 100,
        "offset": 0
    },
    "entities": [
        {
            "typeName": "hive_table",
            "attributes": {
                "owner": "nifi",
                "createTime": 1557832055000,
                "qualifiedName": "demo.test_table@demopilot",
                "name": "test_table"
            },
            "guid": "ecb7bb24-bdde-448c-b718-07273e5ce572",
            "status": "DELETED",
            "displayText": "test_table",
            "classificationNames": [
                "PII"
            ],
            "meaningNames": [],
            "meanings": []
        },
        {
            "typeName": "hive_table",
            "attributes": {
                "owner": "nifi",
                "createTime": 1557832055000,
                "qualifiedName": "demo.test_table@demopilot",
                "name": "test_table"
            },
            "guid": "ed5a9284-c290-4431-ab76-27b820478e29",
            "status": "DELETED",
            "displayText": "test_table",
            "classificationNames": [
                "PII"
            ],
            "meaningNames": [],
            "meanings": []
        },
        {
            "typeName": "hive_column",
            "attributes": {
                "owner": "nifi",
                "qualifiedName": "demo.test_table.traffic_case@demopilot",
                "name": "traffic_case"
            },
            "guid": "73f75a6c-9f4e-41f0-b0ef-6c05ca132639",
            "status": "DELETED",
            "displayText": "traffic_case",
            "classificationNames": [
                "PII"
            ],
            "meaningNames": [],
            "meanings": []
        }
    ]
}

Questions: 1. Is there a API which help to delete all Classifications irrespective of whether they are attached to Entity or not? 2. Delete Single Classification forcefully with Classification Name or GUID?

Running below GET request: http://ip.of.atlas:21000/api/atlas/v2/types/typedefs

& then Delete the guid attached to the typedefs

I tested it out and you could use below API to delete a tag:

curl -k -X DELETE --insecure --negotiate -u :  --header \
''{"classificationDefs":[{"name":"PII","superTypes":[],"attributeDefs":[]}]}' \
'https://atlas-host:21443/api/atlas/v2/types/typedefs?type=classification'
