             Summary: Address WARN log message in ProcessorAuditor on processor RunOnce
                 Key: NIFI-9824
                 URL: https://issues.apache.org/jira/browse/NIFI-9824
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Paul Grey


Noticed a WARN log message while reviewing NiFi logs.  Tracked issue down to `if` block in `updateProcessorAdvice()`.

```
// state is now stopped... consider the previous state
if (ScheduledState.RUNNING.equals(scheduledState)) {
    processorAction.setOperation(Operation.Stop);
} else if (ScheduledState.DISABLED.equals(scheduledState)) {
    processorAction.setOperation(Operation.Enable);
}
```

An additional `else if` is needed to handle the "Run Once" case, where `scheduledState` is "Stopped".  Otherwise, the `processorAction.setOperation()` is never called, which results in an NPE in `NifiAuditor.saveActions()`.

`WARN org.apache.nifi.audit.ProcessorAuditor Unable to record actions: Cannot invoke "org.apache.nifi.action.Operation.name()" because the return value of "org.apache.nifi.action.Action.getOperation()" is null`
