Mark Payne created NIFI-3522:
--------------------------------
Summary: If a Processor clones a FlowFile then adds attributes to
or modifies the clone, a Provenance Event is generated with no FlowFile UUID.
Key: NIFI-3522
URL: https://issues.apache.org/jira/browse/NIFI-3522
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
This can be recreated by adding a SplitText Processor to the canvas and then
feeding it in a FlowFile that does not need to be split. In this case, a
Provenance CLONE event is generated, and so is an ATTRIBUTES_MODIFIED event
because after cloning the incoming FlowFile, we add attributes to the clone.
If we then attempt to query provenance for events generated by this Processor -
or use the Provenance Reporting Task - we will get an error indicating that the
Provenance Event could not be generated because it has no FlowFile UUID.
