Matt Burgess updated NIFI-4707:
-------------------------------
Description:
When the SiteToSiteProvenanceReportingTask emits flow files, some of them
include a "componentName" field and some do not. Investigation shows that only
the components (except connections) in the root process group have that field
populated. Having this information can be very helpful to the user, even though
the names might be duplicated, there would be a mapping between a component's
ID and its name. At the very least the behavior (i.e. component name being
available) should be consistent.
Having a full map (by traversing the entire flow) also opens up the ability to
include Process Group information for the various components. The reporting
task could include the parent Process Group identifier and/or name, with
perhaps a special ID for the root PG's "parent", such as "@ROOT@" or something
unique.
This could also allow for a PG ID in the list of filtered "component IDs",
where any provenance event for a processor in a particular PG could be included
in a filter when that PG's ID is in the filter list.
