[jira] [Commented] (NIFI-5807) ListFTP uncaught exception
[ https://issues.apache.org/jira/browse/NIFI-5807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16711105#comment-16711105 ]
Radim Kučera commented on NIFI-5807:
------------------------------------
Hi! Well I'd already tried almost everything, stracing the nifi app to see if the property file is read included (so I know that readed it is :). I tried single and double quotes and stuff... but escaping the whitespace somehow didn't come into my mind :D Will test that right away. Thanks for your effort anyway!
btw what is a proper way to push this into the NiFi docs? I think that this systemType.property magic should be written all over the Advanced section.
> ListFTP uncaught exception
> --------------------------
>
> 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?
