Either remove or introduce a logger for this instead of system out so we
can control these items with the appropriate logging configs.
> Create a Reporting Task to Send Provenance data
> -----------------------------------------------
>
> Key: MINIFI-13
> URL: https://issues.apache.org/jira/browse/MINIFI-13
> Project: Apache NiFi MiNiFi
> Issue Type: Sub-task
> Components: Data Format, Data Transmission
> Reporter: Joseph Percivall
> Assignee: Joseph Percivall
> Fix For: 0.0.1
>
>
> With initial effort to re-use as much of NiFi as possible it is not possible
> to easily create a ProvenanceReporter to add provenance events as attributes
> to FlowFiles as it would require changing the ProvenancenReporter interface.
> This will require utilizing a different extension point to transmit the
> provenance data back to a core NiFi instance.
> Probably the most efficient way to do this is to create a ReportingTask which
> reports the provenance events using the S2S protocol.
> In the future this will probably be retired as a reporting task as MiNiFi
> grows to rely less on NiFi but this Reporting task could also be contributed
> back to NiFi.
