----------------------------------
Summary: Processor referring to an invalid controller service
flicker between stop and invalid state when attempting to start everything in
the UI
Key: NIFI-14548
URL: https://issues.apache.org/jira/browse/NIFI-14548
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 2.4.0
Reporter: Yuanhao Zhu
Attachments: image-2025-05-08-10-54-05-252.png
We noticed that when a processor is referring to an invalid controller service,
now in nifi 2.x, if we want to start everything within the UI using context
menu e.g.
!image-2025-05-08-10-54-05-252.png!
Then the invalid processor will start to flicker between invalid state and
stopped state, in this case, we cannot even disable the processor itself
anymore. Sometimes when the referred controller service suddenly becomes
invalid e.g. the file no longer exists, then the same flickering issue would
also happen and we get a error message from the toast "processor xxx cannot be
started because it is not stopped. Current state is STARTING"
Would you mind take a look at it? Thanks!
