Nifi UI not launching

avatar
Expert Contributor

Hello

I have downloaded HDF in a centos 7 machine and i have started the service. When i run bin/nifi.sh status, i get the following

Nifi is currently running, listening to Bootstrap on port 40883, PID=18516

However when i enter http://<servername>:8080/nifi the UI fails to appear. Is there anything i am missing? Please advise

Regards

Ahmad

@Ahmad Debbas

As always, start by checking your most recent /logs for ERROR or even WARN, e.g.:

cat nifi-app* | grep ERROR

Logs are: nifi-app*.log, nifi-bootstrap*.log, nifi-user*.log

Milind,

That means some other app is binding to that port. You can edit the nifi.properties file to use a different port or stop the other app that is binding to the port. Do you have HDP components running on this system?

yes I installed Hortonworks Sandbox with HDP2.4 on Oracle VM recently Though the nifi UI was working on Port 8080 but started giving error since yesterday.

I will try changing port and see if it resolve the issue.

Was your VM restarted or the NiFi restarted since HDP was installed?
