We have a NiFi instance running on a remote server where we can only access ports thru SSH Tunneling from another server. So we setup a tunnel for nifi port 9090 and was able to successfully access it from a citrix server using http://localhost:10090/Nifi where port 10090 is tunneling to http://nifiserver:9090/Nifi. This scenario is working. i created input port and a putHDFS on the remote NiFi server and trying to access it from the NiFi instance on the citrix server , i am getting connection timeouts. The dataflow was able to recognise the fact that there is a remote port on the other machine. Also what is the reason behind the calling NiFi needing connectivity to remote port.? it would have been better if that is handled on the remote instance , because it can connect to the web port.(9090 here) . any ideas on what to do.?? 2016-08-18 13:03:40,919 ERROR [Timer-Driven Process Thread-8] o.a.nifi.remote.StandardRemoteGroupPort RemoteGroupPort[name=POV-HDFSInput,target=http://localhost:10090/nifi] failed to communicate with http://localhost:10090/nifi due to java.net.ConnectException: Connection timed out: no further information ...
