With the location of the reset now being where it is placed what happens in
the event that the pulling of state from the state manager results in an
exception? My read is that it would mean we'd not try again to pull the state
later because we cleared the flag but also we'd not have the latest state.
Do you not believe that is possible?

> Key: NIFI-5109
> URL: https://issues.apache.org/jira/browse/NIFI-5109
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.6.0
> Reporter: Maksym Viazovskyi
> Priority: Major
> Attachments:
> 0001-NIFI-2109-Reset-justElectedPrimaryNode-flag-right-af.patch,
> PutAndListSFTP.xml, docker-compose.yml
>
> Original Estimate: 72h
> Remaining Estimate: 72h
>
> AbstractListProcessor stops performing listing of entities when after
> reelection the same node becomes Primary.
> STEPS TO REPRODUCE:
> 0. Make sure that you have docker 18.03.0-ce
> 1. Download attached [^docker-compose.yml] and [^PutAndListSFTP.xml]
> 2. Run *_docker-compose up -d_* in the folder where you downloaded
> docker-compose.yml. This command will run 3 containers - Zookeeper, NiFi
> 1.6.0 in Cluster Mode with 1 node, SFTPs server
> 3. After NiFi is up and running (check http://localhost:8080/nifi) upload
> PutAndListSFTP.xml template and place it on NiFi canvas. It has simple logic
> - generate flow file each 10 seconds and put it on SFTP, in parallel
> ListSFTP processor "listens" for the new files and pushes data about them to
> NiFi log with LogAttribute processor
> 4. Update PutSFTP and ListSFTP processors with password admin (to check SFTP
> container use following credentials SFTP://admin:admin@localhost:2222)
> 5. Run the flow
> 6. Check the NiFi log (*_docker logs -f --tail 100 nifi_*) - you should see
> attributes for the uploaded files on SFTP
> 7. Check that generated each 10 seconds files appear on SFTP /upload folder
> 8. Run following command to restart Zookeeper to put NiFi in reelection
> state: *_docker restart zookeeper_*
> 9. After reelection phase finished check that new files appears on SFTP, but
> NO new files info appears in NiFi log
