Radim Kučera commented on NIFI-5807:
------------------------------------
Hi, thanks for the reply, that looks like a possible solution: but honestly I
tried to create the file and copy it almost everywhere in the nifi directory
(where it seemed to be related to the commons lib) but to no success. And me
not being java programmer, I was not able to verify if this incuding is even
coded in the nifi implementation (spent almost an hour into the git repo :).
Is there any way I can verify the mere fact that the file is being used? I
restarted the service to make sure that its not included only during startup
and so on. Still no luck. Well what about to instruct the nifi.properties to
force downloading it...? No way?

> Key: NIFI-5807
> URL: https://issues.apache.org/jira/browse/NIFI-5807
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.7.1
> Environment: Centos7, OpenJDK Runtime Environment (build
> 1.8.0_181-b13)
> Reporter: Radim Kučera
> Priority: Critical
> Labels: easyfix
>
> Using ListFTP / FetchFTP processors to interact with a slightly bizzare FTP,
> which identifies itself as a "Dopra version: 1.6" but otherwise acts as a
> pretty standard FTP causes following exception.
> By all means this should be at least user-overwritable exception, in a terms
> of "I really don't care what system that is until it works as expected,"
> which is exactly this case.
> As you may expect, it is a vendor stripped down *nix OS Made in China. But
> then again, interacting with it by CLI utilities is fully functional. Is
> there anything that can be fixed in this matter?
