Koji Kawamura updated NIFI-3415:
--------------------------------
Status: Patch Available (was: In Progress)
> Add "Rollback on Failure" property to PutHiveStreaming, PutHiveQL, and PutSQL
> -----------------------------------------------------------------------------
>
> Key: NIFI-3415
> URL: https://issues.apache.org/jira/browse/NIFI-3415
> Project: Apache NiFi
> 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.
