Mark Bean updated NIFI-7231:
----------------------------
Description:
NiFi will not enable all controller services during startup when there are
additional referenced controller services within a controller service.
Specifically, this was observed when the referenced controller services were
dynamic properties.
The enabling process correctly enables referenced services first. However,
during the enabling process, all referencing components are validated. This
creates a situation where the parent controller service is repeatedly validated
for every child controller service. And, part of the validation of the parent
is to validate the child. The circular validation will eventually block;
controller services are not properly enabled; NiFi does not complete the
startup process.

The fix is to not validate the parent controller services unless or until all
child controller services are enabled. Any child service which is not enabled
(regardless of validation) will cause the parent to be invalid. Repeated
validation is not required.
