> 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.
