-----------------------------------
Summary: 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
For the simplest example, with GenerateFlowFile (GFF) -> PutFlowFile (PFF),
where GFF generates FlowFiles with unique ids, and PFF creates local files, GFF
ran 2 times, then following provenance events will be generated:
# GFF CREATE FF1
# PFF SEND file1
# PFF DROP FF1
# GFF CREATE FF2
# PFF SEND file2
# PFF DROP FF2
>From above provenance events, following entities and lineages should be
>created in Atlas, labels in brackets are Atlas type names:
{code}
GenerateFlowFile (nifi_data)
-> GFF, PFF (nifi_flow_path) -> file1 (fs_path)
-> GFF, PFF (nifi_flow_path) -> file2 (fs_path)
{code}
Entities shown in above graph are created. However, those 'nifi_flow_path'
entities do not have inputs/outputs referencing 'nifi_data' or 'fs_path', and
lineage can not be seen in Atlas UI.
