Joseph Witt commented on NIFI-1754:
-----------------------------------

Certainly.  It is a good idea.  I've definitely wanted something similar 
because otherwise for someone debugging something nasty it is all a bit magic.  
So when rollback occurs and it calls the logger this can be more diagnostic 
context it puts out.  Good call for sure.  On the plus side now since we can 
inspect flow file queues at runtime it has taken a bit of the sting out of 
needing this.  Still should do this just pointing out we've put some more tools 
in play.

> Rollback log messages should include the flowfile filename and UUID to assist 
> in flow management.

> When a processor calls rollback on a flowfile, the filename and UUID of the 
> flowfile should be included in log entry to make it easier for the offending 
> files to be found and fixed or removed from the flow by the dataflow managers.
