Re: Apache Nifi Installation Issues

[Alex Becker]

Hey Mike,

Thanks for the response.  Apparently OneDrive was the culprit, I had Nifi
in a OneDrive directory which I have mounted back to my WSL via /mnt/c, and
when I moved to a local directory on my C disk it worked fine.  Not sure
what the issue is, the permissions should be the same on the OneDrive
directory as far as WSL is concerned, but maybe something else is at work

In any event, thanks for the help!

Re: Apache Nifi Installation Issues

[Michael Moser]

Alex,

The error occurs when NiFi tries to move the self-signed certificate it
generated from /tmp/test-keystore-4089669996254362100.p12 to
./conf/keystore.p12.  This is a very basic file operation, so something is
up with your environment.

I have not used WSL, so I suggest Googling "windows subsystem for linux
tmpdir not working" and see if you can find any tips for making your /tmp
directory readable by NiFi.

Good luck,
-- Mike

Apache Nifi Installation Issues

[Alex Becker]

Howdy all,

I am trying to get an instance of Apache Nifi up and running on my laptop.
This is a Windows machine issued by my company, but I am attempting to run
the Linux binary for Nifi from my Ubuntu 20.04 WSL, where I do all of my
development.  I have tried multiple different versions, including 1.24.0,
1.23.3, and 1.18.0, all with Java version 11.0.21 and Java 1.8.0_392.  I
get the same error on all builds:

2023-12-28 08:01:28,727 ERROR [main] org.apache.nifi.bootstrap.Command
Self-Signed Certificate Generation Failed
java.nio.file.NoSuchFileException:

at org.apache.nifi.bootstrap.RunNiFi.start(RunNiFi.java:1271)
at org.apache.nifi.bootstrap.RunNiFi.main(RunNiFi.java:302)

I believe this is the source of why my Nifi binary is failing to start.  I
have verified that the directory Nifi is trying to access has the correct
permissions, so I am at a bit of a loss for how to resolve this issue.

Would greatly appreciate any help in resolving this issue.  Apologies, I am
getting an error when attempting to attach the full application logs for
whatever reason, so hopefully the above snippet is helpful.
Let me know if you need anything else,

Thanks!
Alex

Re: NiFi installation issues

[Pushkara R]

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.

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)

Pushkar

Any chance you can look and provide relevant logs? You can find them in the 
/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

NiFi installation issues

[Pushkara R]

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 

Could someone please help me debug this?

Thank You
Pushkar

Re: Nifi Installation issues

Hi Afsar,

It appears that when you were running the installation, your machine was unable 
to connect to the Maven Repository in order to download the necessary 
dependencies.

You can troubleshoot connecting to the repository using these steps [1].
