If I create 2 instances that have references between them in one call, it fails
with the following exception:
SEVERE: org.apache.atlas.typesystem.exception.EntityNotFoundException: Could
not find vertex for Class Reference (type:
ConnectorDirectoryModel_OMRSConnectorDirectory, id: <unassigned>)

Example:
I have the types as follows (Catalog has reference called connectorDirectory to
ConnectoryDirectory class):
{
"typeName": "CatalogModel_OMRSCatalog",
"definition": {
"classTypes": [
{
"hierarchicalMetaTypeName":
"org.apache.atlas.typesystem.types.ClassType",
"typeName": "CatalogModel_OMRSCatalog",
"typeDescription": "",
"attributeDefinitions": [
{
"name": "connectorDirectory",
"dataTypeName":
"ConnectorDirectoryModel_OMRSConnectorDirectory",
"multiplicity": "required",
"isComposite": false,
"isUnique": false,
"isIndexable": false,
"reverseAttributeName": null
}
]
}
]
},
}
If I create ConnectorDirectory first and then create Catalog, it works (note
that while creating Catalog, the ConnectorDirectory has ID):
[
{
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
"id": {
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
"id": "-1468998004536470000",
"version": 0,
"typeName": "ConnectorDirectory"
},
"typeName": "ConnectorDirectory",
"values": {
"name": "DefaultConnectorDirectory",
},
}
]
[
{
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
"id": {
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
"id": "-1468998006314995000",
"version": 0,
"typeName": "Catalog"
},
"typeName": "Catalog",
"values": {
"connectorDirectory": {
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
"id": {
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
"id": "6b7f8949-f5ad-453b-bc57-e8929cc9dd2c",
"version": 0,
"typeName": "ConnectorDirectory"
},
"typeName": "ConnectorDirectory",
"values": {
"name": "DefaultConnectorDirectory",
},
},
"name": "DefaultCatalog",
},
}
]
But, If I create both Catalog and ConnectorDirectory in one call, it fails (in
this case the connectorDirectory does not have ID):
[
{
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
"id": {
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
"id": "-1468998163729034000",
"version": 0,
"typeName": "Catalog"
},
"typeName": "Catalog",
"values": {
"connectorDirectory": {
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
"id": {
"jsonClass":
"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
"id": "-1468998163731032000",
"version": 0,
"typeName": "ConnectorDirectory"
},
"typeName": "ConnectorDirectory",
"values": {
"name": "DefaultConnectorDirectory",
},
},
"name": "DefaultCatalog",
},
}
]
