How to resolve `java.net.BindException: Address already in use` error while accesing kafka connect in Apache kafka ?

rk241091 — Tue, 05 Jun 2018 16:57:40 GMT

When trying to use kafka connect using following command :

bin/connect-standalone.sh config/connect-standalone.properties config/connect-file-source.properties config/connect-file-sink.properties

It throws a error as
`WARN FAILED http_8083@773e2eb5{HTTP/1.1}{0.0.0.0:8083}: java.net.BindException: Address already in use (org.eclipse.jetty.util.component.AbstractLifeCycle:212)`

and finally ends with the line `INFO Kafka Connect stopped`

How can I change my Kafka-Connect port from 8083 to other port ?

Hey @Rahul Kumar!
You can change this in connect-standalone.properties

Should have a property called rest.port 🙂

or if you're planning to use kafka connect in the cluster mode, you should find this parameter in connect-distributed worker.properties

Hope this helps!

@Rahul Kumar You can change the port by adding:

rest.port=<port>

To the config/connect-standalone.properties

Good to know @Rahul Kumar!
I already used in cluster mode and it's quite good as well.
So keep going on this! It's an interesting feature from kafka

PS: I'm not an expert yet haha, just a humble guy trying to help xD

@Vinicius I m right now at a beginner stage of learning kafka. Just running a single instance on my local system ...havn't thought of working on clusters. But It is nice to get in touch with u and enhance my knowledge.

Thanks once again 🙂
