Any insights?

Another instance is running and blocking in background.

Check running processes and kill them

ps -ef | grep nifi 

after that, restart.

HI @Faerballert 

Thanks for reply.

I cannot find another instance running on the background.

I have killed the processes and restarted Nifi but still the same error message.

Hi @Faerballert ,

Yes you are correct. Issue is resolved after restart of the Nifi node.

Hello Faerballert!  Sorry to barge into this thread.  I am also receiving this same error.  When I run the command you recommended, I obtain the following result:

dave@nificlient1:~/tools/nifi-1.19.1-bin/nifi-1.19.1/bin$ ps aux | grep nifi
avahi 1026 0.0 0.0 7756 3840 ? Ss 13:59 0:00 avahi-daemon: running [nificlient1.local]
dave 462448 0.0 0.0 6608 2228 pts/0 S+ 16:01 0:00 grep --color=auto nifi

How can i successfully kill these processes?

Thank you!

VR,

Dave

What I am tryin mg to do is install a nifi cluster onto 3 Ubuntu 22.04 clients. I first installed nifi on each client independently. And then attempted to install a cluster using the same clients…I first stopped the nifi service running on each of the clients before attempting to install a cluster. 

Should I not install nifi separately on each of the clients before attempting to install the cluster?

thank you for any guidance
