Hi, I have a Kafka server deployed on google cloud VM. It is getting data from a kafka (python) producer running on a remote machine that is connected to the VM through a VPN. I added VPN's tunnel interface's IP as advertised listener in kafka server properties so that client can connect to the kafka server and start data ingestion.
Now when I stop kafka server, comment out advertised listener from the properties and restart it, incoming data does not stop. However, recently I had to restart google cloud machine so I stopped the server and client. When I restarted the client, I started to get the following error: Error creating producer object: getaddrinfo failed for kafka-server:9092, exception was [Errno 8] hostname nor servname provided, or not known. Is your advertised.listeners (calledadvertised.host.name before Kafka 9) correct and resolvable? After I added advertised listener again, the issue got resolved. So, I am wondering, why didn't the data stop when I removed 'advertised listeners' from server properties for the first time? Is this the intended behavior? Does 'advertised listeners' parameter become ineffective once the connection is established? How does kafka maintain a connection with the client even after server restart? I am using kafka 0.10.1 Thanks, Faraz
