> Currently duplicate keys can exist in the nifi.properties file and you aren't
> necessarily guaranteed or sure which value will be used when the system
> starts. There is already a method in NiFiProperties.java for validation at
> startup. Logic should be added so that when duplicates are encountered the
> system is not permitted to start. Also include a good log message to say what
> the duplicates are and what the issue was.
