Description

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
