I am using kafka confluent for my project. When I run kafka-connect command, I always get Address already in use response although I don't use 8003 port. Despite I still can use this feature with original kafka. Anyone can help me? Thanks!
As per kafka-connect docs the default port "rest.port" is 8083
So are you getting conflict on port 8003 (or there is a typo ? is it 8083)
Can you try changing the "rest.port" in your worker config to something else and then try again.
Also please try to run the below commands before starting kafka-connect to verify if there is any port conflict? Or if there are any bind address issue
# netstat -tnlpa | grep 8083 # netstat -tnlpa | grep 8003
