-------------------------------------------
Summary: Handle controller service 'Scheduled State' after upgrade
to NiFi 1.16
Key: NIFI-11028
URL: https://issues.apache.org/jira/browse/NIFI-11028
Project: Apache NiFi
Issue Type: Bug
Components: NiFi Registry
Affects Versions: 1.16.0
Reporter: Zsihovszki Krisztina
It is not possible to revert local changes on an upgraded flow if the
controller services are enabled. The following error is reported: "Cannot
modify Controller Service configuration because it is currently enabled. Please
disable the Controller Service first."
The "Scheduled State" of a controller service was not stored prior to 1.16.
When NiFi is upgraded from an earlier version to 1.16, the stored "Scheduled
State" of controller services in the flow is "null", while the actual (local)
scheduled state is ENABLED/DISABLED (both is mapped to DISABLED at comparison).
When "Revert local changes" is selected, the "Scheduled State" change is noted
as a difference between the proposed and currently loaded flow.
{code:java}
Controller Service 10f21a4c-194f-34c2-8cfc-97892f73d3ec has a Scheduled State
of null in Proposed Flow but DISABLED in Currently Loaded Flow{code}
Since it's considered a local change, the controller service is not disabled
before the flow is synchronized and when synchronization takes place, the
"Cannot modify Controller Service configuration because it is currently
enabled. Please disable the Controller Service first." occurs.
