-------------------------------
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`
