Question

Nifi 2.0 Start Problem

Hello , 

I use "nifi.cmd start" to start with NIFI.

Sometime  it works and most of the times it doesn't. 

In case  where NIFI doesn't work I am getting following logs :

2024-11-29 21:06:39,642 INFO [main] o.a.n.w.StandardContentViewerApplication Starting StandardContentViewerApplication using Java 21.0.2 with PID 24600 (D:\WorkingInstaller\2.0\nifi-2.0.0-bin\nifi-2.0.0\work\jetty\nifi-standard-content-viewer-2.0.0.war\webapp\WEB-INF\classes started by Riyaz in D:\WorkingInstaller\2.0\nifi-2.0.0-bin\nifi-2.0.0)
2024-11-29 21:06:39,643 INFO [main] o.a.n.w.StandardContentViewerApplication No active profile set, falling back to 1 default profile: "default"

 

Any pointers would be appreciated.

Thanks,

Riyaz

    I have a same problem.  Nifi.sh started and failed in next few seconds.

    2025-12-31 14:03:57,387 INFO [main] org.apache.nifi.bootstrap.Command Application Process [9606] started
    2025-12-31 14:03:57,388 INFO [main] org.apache.nifi.bootstrap.Command Bootstrap Process Running

    2025-12-31 14:04:57,392 WARN [StartBootstrapCommand] o.a.n.b.command.StartBootstrapCommand Application monitoring failed with status [STOPPED]

    nifi can't start with Java17 but Java21

    Any pointers would be appreciated

    @mohdriyaz 

    These are just INFO level log lines.   What logging did you see in the NiFi bootstrap.log?  
    Does the process die or does just appear hung and not progressing to point where UI is becomes available?

    On the times where NiFi did start, what log lines are seen immediately after above are output?

    Thanks,
    Matt

    I attach a screenshot of the log when the start succeeds.

      @Dahlgren 

      - Make sure you are using a Java 21 JDK and not a Java 21 JRE.
      - Try excluding the NiFi directory to include all the repositories from your Virus scanning software and see if that helps resolve the startup issue.

      Here is an Apache NiFi slack thread discussing this same issue:

        I found one solution ... ( not the correct way)

        just  remove nifi-standard-content-viewer-nar-2.0.0.nar from Lib folder and it will start working.

        Only issue with this approach is that you cannot view the flow file contents in JSON or any other format. You can view it only in Hex format (default)
