]
Radim Kučera updated NIFI-5807:
-------------------------------
Description:
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?
