@Madhan Neethiraj I'm having problems getting the tag policy to work. Here are the steps I've taken: Disabled resource policies - holger_gov cannot select on default and foodmart database Created a tag called tennant_xxx Created a tag policy giving access to holger_gov if tag is tennant_xxx - so far so good as holger_gov now has select access Created a tag called DATA_ZONE with attribute name (type string) and added to default and footmart database - one with a name = data_lake and one with name = staging Added policy condition: ctx.getAttributeValue("DATA_ZONE", "name").equals("data_lake") But holger_gov can still select on both databases - I only want the data_lake one to be selectable. I have tried various combinations to try to get it to work including the below, but to no avail. Any ideas? if(ctx.getAttributeValue("DATA_ZONE", "name").equals("data_lake")) { ctx.result = true; } else { ctx.result = false; } ... View more

Thanks, @Madhan Neethiraj - that's very helpful indeed. And I like your suggestion about how to structure the Ranger policies - very logical. I will try this out and will post back if I have any other queries about this. ... View more

@Eyad Garelnabi - Will the optionality on tag propagation be system wide, or would it be possible to exclude some tags from being propagated whilst propagating others? ... View more

I'm posting this in case anyone finds it useful. There's now a way for metamodels to inherit values from other values, but in 0.8 you can use the qualifiedName instead of the guid, which is much better. Type POST http://127.0.0.1:21000/api/atlas/v2/types/typedefs { "enumDefs":[], "structDefs":[], "classificationDefs":[], "entityDefs":[ { "superTypes":[ "DataSet" ], "name":"test_entity_18", "description":"test_entity_18", "attributeDefs":[ { "name":"test_18", "isOptional":true, "isUnique":true, "isIndexable":false, "typeName":"string", "valuesMaxCount":1, "cardinality":"SINGLE", "valuesMinCount":0 }, { "name":"test_18_db", "isOptional":true, "isUnique":true, "isIndexable":false, "typeName":"hive_db", "valuesMaxCount":1, "cardinality":"SINGLE", "valuesMinCount":0 } ] } ] } Entity POST http://127.0.0.1:21000/api/atlas/v2/entity { "entity": { "typeName": "test_entity_18", "createdBy": "admin", "updatedBy": "admin", "attributes": { "description": "test decription", "name": "test_entity_18", "owner": "admin", "qualifiedName": "test_entity_18", "test_18": "attr1", "test_18_db": { "typeName": "hive_db", "uniqueAttributes": { "qualifiedName": "default@Sandbox" } } }, "guid": -1 }, "referredEntities": {} } I learnt this from here - https://issues.apache.org/jira/browse/ATLAS-1506 ...

Thank you, that helps enormously! I'm obviously doing something wrong with the GET /v2/entity/uniqueAttribute/type/{typeName} I created an entityDefs type called test_entity_15. I then created an entity called test_entity_15. { "enumDefs":[], "structDefs":[], "classificationDefs":[], "entityDefs":[ { "superTypes":[ "DataSet" ], "name":"test_entity_15", "description":"test_entity_15", "attributeDefs":[ { "name":"test_15_1", "isOptional":true, "isUnique":true, "isIndexable":false, "typeName":"string", "valuesMaxCount":1, "cardinality":"SINGLE", "valuesMinCount":0 } ] } ] } { "entity": { "typeName": "test_entity_15", "attributes": { "description": "test_entity_15", "name": "test_entity_15_1", "owner": "admin", "qualifiedName": "test_entity_15@Sandbox", "test_15_1": "attr1" }, "guid": -1 }, "referredEntities": {} } But when I try GET http://127.0.0.1:21000/api/atlas/v2/entity/uniqueAttribute/type/test_entity_15 I get this error. { "errorCode": "ATLAS-400-00-013", "errorMessage": "Type test_entity_15 with unique attribute does not exist" } I set "isUnique" to true, so I'm not sure what else is preventing the unique attribute! Also, I created a JIRA due to the createdBy and updatedBy inconsistency between type and entity POSTs- https://issues.apache.org/jira/browse/ATLAS-1895 ... View more

Thank you for you're help @Ashutosh Mestry and @Sarath Subramanian. And apologies for the late response. For anyone who is interested, here's what happened when I posted the entity. Response: { "mutatedEntities": { "CREATE": [ { "typeName": "test_entity_7", "attributes": { "qualifiedName": "test_entity_7_hw@Sandbox" } , "guid": "01960675-149f-43da-bdb8-da79058beb51", "status": "ACTIVE" } ], } , "guidAssignments": { -1: "01960675-149f-43da-bdb8-da79058beb51" } } GET http://127.0.0.1:21000/api/atlas/v2/entity/guid/01960675-149f-43da-bdb8-da79058beb51 { "referredEntities": { } , "entity": { "typeName": "test_entity_7", "attributes": { "owner": "admin", "test_7_2": "attr2", "test_7_1": "attr1", "qualifiedName": "test_entity_7_hw@Sandbox", "name": "test_entity_7_hw", "description": "test decription" } , "guid": "01960675-149f-43da-bdb8-da79058beb51", "status": "ACTIVE", "createdBy": "holger_gov", "updatedBy": "holger_gov", "createTime": 1498267676098, "updateTime": 1498267676098, "version": 0, "classifications": [], } } I'm just testing in a sandbox and using Chrome apps 'Advanced REST client'. Is this why createdBy and updatedBy is set to holger_gov? If I set the createdBy and updatedBy I still get the holger_gov: POST http://127.0.0.1:21000/api/atlas/v2/entity { "entity": { "typeName": "test_entity_7", "createdBy": "admin", "updatedBy": "admin", "attributes": { "description": "test decription", "name": "test_entity_7_hw_admin", "owner": "admin", "qualifiedName": "test_entity_7_hw_admin@Sandbox", "test_7_1": "attr1", "test_7_2": "attr2" }, "guid": -1 }, "referredEntities": {} } Response { "mutatedEntities": { "CREATE": [ { "typeName": "test_entity_7", "attributes": { "qualifiedName": "test_entity_7_hw_admin@Sandbox" } , "guid": "ed9cf696-cd76-4814-a407-9fdb8d18da3c", "status": "ACTIVE" } ], } , "guidAssignments": { -1: "ed9cf696-cd76-4814-a407-9fdb8d18da3c" } } GET http://127.0.0.1:21000/api/atlas/v2/entity/guid/ed9cf696-cd76-4814-a407-9fdb8d18da3c { "referredEntities": { } , "entity": { "typeName": "test_entity_7", "attributes": { "owner": "admin", "test_7_2": "attr2", "test_7_1": "attr1", "qualifiedName": "test_entity_7_hw_admin@Sandbox", "name": "test_entity_7_hw_admin", "description": "test decription" } , "guid": "ed9cf696-cd76-4814-a407-9fdb8d18da3c", "status": "ACTIVE", "createdBy": "holger_gov", "updatedBy": "holger_gov", "createTime": 1498268595794, "updateTime": 1498268595794, "version": 0, "classifications": [], } } Also, how do I use /v2/entity/bulk? I get the following error: { "errorCode": "ATLAS-404-00-005", "errorMessage": "Given instance guid {0} is invalid/not found" } I currently can't find a way of returning the GET for an attribute without first copying the guid when I first create it!!! ...
