I've had this problem with an old version for some time (I'm really
concentrating more on NiFi 1.x now) and I have to fix it. I'm pulling my
hair out a bit. We eliminated all use of ProcessorLogeven in this older
code that we're trying to keep running on 0.7.1 and maintaining when we
must.
In /nifi-api-0.7.1.jar/ there is certainly ComponentLog.class, but on
starting NiFi, I keep getting what's below in /nifi-app.log/.

To answer the obvious questions...
public class *ContentIdentifier* extends BaseIdentifierProcessor
In onTrigger(), there is this lone use:
getLogger().error( message );
public abstract class BaseIdentifierProcessor extends AbstractProcessor
There is no use of any logger in this class. You already know
AbstractProcessor.
Is there something I'm missing?
