Adding New NiFi Provenance Policies

Apache NiFi 1.7.0 introduces new policies for controlling access to provenance events from a component. When upgrading to Apache NiFi 1.7.0 these new policies will not exist. As a result, users who could previously access provenance events will no longer have access to these provenance events. To ensure continued user access to provenance events, a NiFi administrator must update NiFi policies after upgrade.

By introducing the new view provenance events policy for controlling access to the event itself these operators can better understand the dataflow and track what is happening while the administrators can still maintain tight control of the flowfile attributes and content. To avoid users losing access to provenance event information, perform the following steps:
  1. Create new view provenance policies for your components.
  2. Assign users to the new policies.
Users can now resume provenance event access.
