I'd like to define and create a new meta model in Atlas.
I would like it to store a date and a value, but also inherit values from existing types: hive tables and dbs.
I can create new simple types and entities, but I'm having problems getting the right behaviour for the hive tables and dbs.
I when I create a simple type with 'superTypes' of Asset and Referenceable I'm able to create simple entities. But when I use DataSet I get errors.
Here's a type I tried (I get get values and dates to work so this is just trying to get the hive_db attribute to work):
{
"enumTypes": [],
"structTypes": [],
"traitTypes": [],
"classTypes": [
{
"superTypes": [
"DataSet"
],
"hierarchicalMetaTypeName": "org.apache.atlas.typesystem.types.ClassType",
"typeName": "test_type_class_22",
"typeDescription": null,
"attributeDefinitions": [
{
"dataTypeName": "hive_db",
"isComposite": false,
"isIndexable": true,
"isUnique": false,
"multiplicity": "required",
"name": "db",
"reverseAttributeName": null
}
]
}
]
}
But I don't know how to properly create values that point to the actual 'default' database.
{
"jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
"id":{
"jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
"id":"-1566683608564093000",
"version":0,
"typeName":"test_type_class_22",
"state":"ACTIVE"
},
"typeName":"test_type_class_22",
"values":{
"name":"default"
"qualifiedName":"default@Sandbox",
"description":"test description",
"owner":null,
"db": "default"
},
"traitNames":[
],
"traits":{
}
}
For the value of 'db' (which is of datatype hive_db) I tried "default", "default@Sandbox", "default.test_type_class_22@sandbox" and "da862503-62f0-41a6-8acc-da4efcf856eb". I just don't know what I should be setting this to. Any ideas? All return the error similar to:
