While going through the apache official page

https://kafka.apache.org/quickstart

A text file is created as

echo -e "foo\nbar" > test.txt

And to use kakfa connect following command is used

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

But while above command gets executed it shows a message kafka-connect stopped

  • Yes, already all the codes and page description is mentioned in the question along with problem screen shot for clearance @Rob Thank you – RAHUL KUMAR Jun 04 '18 at 12:27
  • `Address already in use`... Not a Kafka problem. You're running something else that conflicts with it – OneCricketeer Jun 04 '18 at 13:08
  • @cricket_007 I killed the initial `test` topic created, deleted the offsets then started kafka again it is showing `WARN FAILED org.eclipse.jetty.server.Server@652ce654: java.net.BindException: Address already in use` and `Kafka Connect stopped` . How to rectify this ? – RAHUL KUMAR Jun 05 '18 at 09:17
  • You must stop the other process running on that port. I cannot tell you what that is based on the information provided. Your port is 8083 https://stackoverflow.com/a/12737392/2308683 You *could* change the Kafka Connect port... Look in the property files for 8083, and pick a different number like 8084 – OneCricketeer Jun 05 '18 at 12:11

Something else is using the same port that Kafka Connect wants to use.

You can use netstat -plnt to identify the other program (you'll need to run it as root if the process is owned by a different user).

If you want to get Kafka Connect to use a different port, edit config/connect-standalone.properties to add: 

rest.port=18083

Where 18083 is an available port.
