NIFI-4971: ReportLineageToAtlas complete path can miss one-time lineages
- Separated Hook message de-duplication logic from NiFiAtlasHook to
NotificationSender
- NiFiAtlasHook used to send individual CREATE_ENTITY messages for each
entities,
this commit changed it to bundle all new entities into a single
CREATE_ENTITY to preserve entity creation order, so that new DataSet
entities can be referred from new nifi_flow_path entities
- Added more unit tests
This closes #2542

> ReportLineageToAtlas 'complete path' strategy can miss one-time lineages

> Key: NIFI-4971
> URL: https://issues.apache.org/jira/browse/NIFI-4971
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.5.0
> Reporter: Koji Kawamura
> Assignee: Koji Kawamura
> Priority: Major
>
> For the simplest example, with GetFlowFIle (GFF) -> PutFlowFile (PFF), where
> GFF gets files and PFF saves those files into a different directory, then
> following provenance events will be generated:
> # GFF RECEIVE file1
> # PFF SEND file2
> From above provenance events, following entities and lineages should be
> created in Atlas, labels in brackets are Atlas type names:
> {code}
> file1 (fs_path) -> GFF, PFF (nifi_flow_path) -> file2 (fs_path)
> {code}
> Entities shown in above graph are created. However, the 'nifi_flow_path'
> entity do not have inputs/outputs referencing 'fs_path', so lineage can not
> be seen in Atlas UI.
