@mattyb149 As we discussed at #1677, I've added Rollback on Failure to
PutDatabaseRecord. I changed many lines of code, but those are basically
refactoring on error handling and dividing the existing onTrigger method into
several parts for better manageability and clearer execution paths.
I also added context yielding when Rollback on Failure is engaged. Because
without doing penalization nor yielding, the failing FlowFile retries too
frequently.
Would you review this again? Please let me know your feedback. Thank you!

> Issue Type: Improvement
> Reporter: Matt Burgess
> Assignee: Koji Kawamura
>
> Many Put processors (such as PutHiveStreaming, PutHiveQL, and PutSQL) offer
> "failure" and "retry" relationships for flow files that cannot be processed,
> perhaps due to issues with the external system or other errors.
> However there are use cases where if a Put fails, then no other flow files
> should be processed until the issue(s) have been resolved. This should be
> configurable for said processors, to enable both the current behavior and a
> "stop on failure" type of behavior.
> I propose a property be added to the Put processors (at a minimum the
> PutHiveStreaming, PutHiveQL, and PutSQL processors) called "Rollback on
> Failure", which offers true or false values. If set to true, then the
> "failure" and "retry" relationships should be removed from the processor
> instance, and if set to false, those relationships should be offered.
> If Rollback on Failure is false, then the processor should continue to behave
> as it has. If set to true, then if any error occurs while processing a flow
> file, the session should be rolled back rather than transferring the flow
> file to some error-handling relationship.
> It may also be the case that if Rollback on Failure is true, then the
> incoming connection must use a FIFO Prioritizer, but I'm not positive. The
> documentation should be updated to include any such requirements.
