------------------------------------
Summary: Unable to view Component ID of "unknown" components in a
provenance lineage graph.
Key: NIFI-2769
URL: https://issues.apache.org/jira/browse/NIFI-2769
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.0.0
Reporter: Matthew Clarke
Priority: Minor
NiFi lineage that includes unknown components does not provide the minimum
level of information needed to troubleshoot a dataflow in a secured NiFi user
level component access policies. Clicking on "view details" of an "unknown"
component in a lineage graph returns an unauthorized response. User Should be
able to at least retrieve the UUID for the unknown components.
An example use case:
A user (user M) has permissions to a process group with an input port. That
input port is fed by many different parent level connections from other
components user M does not have permission to. If user M performs a lineage
search against a single FlowFile, it is not possible for user M to determine
which of source connections the data came from. This makes troubleshooting
difficult as user must query all source dataflow users to do queries to see if
they were the source of the data.
