[jira] [Updated] (NIFI-11978) NPE when trying to disable Management Controller Service
[ https://issues.apache.org/jira/browse/NIFI-11978?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tamas Palfy updated NIFI-11978:
-------------------------------
Description:
With https://issues.apache.org/jira/browse/NIFI-11556 controller services implement the GroupedComponent interface. However Management Controller Services (the ones available and managed from the Controller Settings) don’t have groups.
Not sure about the extent of the issues but I can confirm a concrete one: the management controller services can’t be disabled because that requires a check of the referencing components and the logic includes
{code:java}
public class StandardControllerServiceDAO extends ComponentDAO implements ControllerServiceDAO {
...
@Override
public void verifyUpdateReferencingComponents(final String controllerServiceId, final ScheduledState scheduledState, final ControllerServiceState controllerServiceState) {
final ControllerServiceNode controllerService = locateControllerService(controllerServiceId);
controllerService.getProcessGroup().verifyCanScheduleComponentsIndividually();
{code}
which throws NullPointerException (as there is no process group).
