NiFi installation issues
Hi,
I'm installing NiFi on my arch linux machine following the instructions in
https://github.com/apache/nifi.
After I built the project, I executed the NiFi startup script and tried
connecting to the local server but I got a 404 error with the following
message.
HTTP ERROR: 404
Problem accessing /nifi/. Reason:
Not Found
------------------------------
Powered by Jetty:// 9.3.9.v20160517 <http://eclipse.org/jetty>
Could someone please help me debug this?
Thank You
Pushkar

I notice that the server takes a minute or so to come up after running
nifi.sh start. I think the first few times I tried running nifi, I tried
connecting to the server immediately after running nifi.sh. Obviously I
couldn't connect as the server wasn't up yet. Maybe I tried to rerun the
script which could have caused clashes for the 8080 port.
This is just a guess, I'm not sure if this is the reason. But everything
seems to be working fine now. Thanks a lot Oleg.

Thanks for pointing that out Oleg. I'll see what's occupying that port.

It appears that something is running on port 8080 so Jetty can not start. You can see at the bottom of the log the following (see below)
1.
2017-01-09 17:24:23,606 WARN [main] org.apache.nifi.web.server.JettyServer Failed to start web server... shutting down.
2.

Any chance you can look and provide relevant logs? You can find them in the <NIFI_HOME>/log directory.
Also, could you please be more specific as to what directions did you follow. Just want to make sure that if there are any issues with documentation it is corrected.
Cheers
Oleg
