> When enabling a FileChangeNotifier, it's easy to forget uncommenting the *nifi.minifi.notifier.file.config.path* property (required). Minifi restart will throw an unfriendly error:
> {noformat}
> Exception in thread "main" java.lang.IllegalArgumentException: Property, nifi.minifi.notifier.file.config.path, for the path of the config file must be specified.

> Expected: improve the error message to be meaningful and suggest the user configure the property. No stacktrace, as we know what's going on exactly.
