> Expression language is not supporting Hostname property in FetchFTP
> -------------------------------------------------------------------

> Key: NIFI-4025
> URL: https://issues.apache.org/jira/browse/NIFI-4025
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.2.0
> Environment: ubuntu 14 x86_64 jdk1.8 nifi1.2.0
> Reporter: Roman Biryulkin
> Priority: Major
> Attachments: nifi-app.log.JPG, tcpdump.JPG

>
> It is not possible to use a single FetchFTP processor instance with multiple
> FTP servers, because expression language is not supporting Hostname property.
> Ways to reproduce:
> Step 1: Use ip address of my ftp server in property Hostname.
> Result: Success fetch files, no errors in log
> Expected: Success fetch files, no errors in log
> Step 2: I use MiNiFi and processor ListFile on it. FlowFile have attribute
> "s2s.host". I set value "$\{s2s.host}" in property Hostname.
> Result: Files failed to load.
> - In nifi-app.log I see error: "java.net.ConnectException: Connection refused
> (Connection refused)", but with right ip address.
> - On the right network interface not see any traffic for ftp port (command on
> ubuntu: tcpdump -i eth0 port 21)
> - On the local network interface I see outgoing traffic to ftp port (command
> on ubuntu: tcpdump -i lo port 21)
> Expected: Success fetch files, no errors in log
