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 > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
