Joseph Percivall commented on NIFI-1196:
----------------------------------------
This patch causes an error in the UI. If you create a file with a parent and
emit a fetch provenance event for that newly created file then when you try to
view the lineage of the resulting flowfile you get this message:
Found cycle in graph. This indicates that multiple events were registered
claiming to have generated the same FlowFile (UUID =
57922e2a-ac07-4574-a71e-b1a3a7b6cff5)
This is due to this line:

> FETCH Events are not properly handled in the framework and UI

> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework, Core UI
> Affects Versions: 0.3.0
> Reporter: Aldrin Piri
> Assignee: Aldrin Piri

>
> When the FETCH ProvenanceEventType was incorporated some of its handling was
> not propagated throughout the framework. This is chiefly inclusive of:
> * Presenting transit uri in the Provenance event info within the UI
> * Writing/Reading provenance events into the StandardRecordReader/Writer
> * Handling in the StandardProcessSession for counting flowfiles in/out and
> their bytes
> The net result is that unique properties, in this case believed to be only
> transit URI were never persisted and/or received.
