Apache Nifi: ListenHTTP - Address already in use Exception

Contributor

I'm trying to run listenHTTP processor for listening to a webhook notification. 

I'm relatively new to this processor. When I initialize, I observe java.net.bind exception. Address already in use. 

 

nifi url: http://localhost:8080/nifi/    (it has a public IP but we use NATing) 

 

Existing configuration

Before starting processor ListenHHTP , please check and make sure port 8888 is not used by any other process at host where nifi service is running.

You can use netstat command to check and confirm.

Hi @ckumar 

Yes I have verified. The port is not being used. However nifi throws the error.
