Aldrin Piri created NIFI-1181:
---------------------------------
Summary: Core attributes should be guarded
Key: NIFI-1181
URL: https://issues.apache.org/jira/browse/NIFI-1181
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 0.3.0
Reporter: Aldrin Piri
Evaluating some work for UpdateAttributes, specifically the ability to delete
attributes, led to being able to delete UUID
(https://github.com/apache/nifi/pull/116)
As a result, the framework was nonplussed at the missing core attribute, uuid:
{quote}
12:53:35 ESTERROR6d65c083-eb22-4ae7-b542-de808b1402d0
UpdateAttribute[id=6d65c083-eb22-4ae7-b542-de808b1402d0]
UpdateAttribute[id=6d65c083-eb22-4ae7-b542-de808b1402d0] failed to process
session due to java.lang.IllegalStateException: Cannot create Provenance Event
Record because FlowFile UUID is not set: java.lang.IllegalStateException:
Cannot create Provenance Event Record because FlowFile UUID is not set
{quote}
Not sure if this applies to other core attributes, but at minimum, it seems
like the UUID needs to have some framework level guarding against it from being
inappropriately modified.
