Kafka connect not working ?

[#1]

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

It has stopped because the "address is already in use" That means it can't bind because the port is in use.
Kill the process and restart
