Welcome to the community.

Can you share more details.

1. Try using the  latest Apache NiFi 2.1.0 release instead of the very first unofficial maintenance release 2.0.0.
2. Does the processor show as valid?
3. From the server running NiFi, can you resolve and connect to the FTP server via command line?
4. Do any of the files on the FTP server have a last modified timestamp newer then 3 hours old?  
5. Try changing "Entity Tracking Initial Listing Target"  from "tracking time window" to "All available".   Does it produce a FlowFiles?
6. When you start listFTP processor, does it indicate an active running thread in the upper right corner?
7. What do you see in the nifi-app.log when processor runs?  Any exceptions?
   Try puttingg this processor class (org.apache.nifi.processors.standard.ListenFTP) in DEBUG in the NiFi logback.xml file to get additional logging output.
8. With using "tracking timestamps" instead does it produce flowfiles?

Hopefully some of the above checks can help narrow focus of where the issue exists.

Thanks you,

Matt

Looping back on number 6.  When you see the active thread indicated in the upper right corner, do you see tasks as completing or the thread just remains active all the time?

Do you see any data being written to your Redis distributed map cache server?

Thanks,
Matt
