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 ?

Okay ! after a bit of search on stackoverflow I came across the command `sudo chown -R $USER:$USER /home/rahul/nifi-1.6.0` that will give the permission to the folder to alter the changes with permission to read and write, and Bingo !!! it worked . And after firing the command mentioned in above, there is no error as following : Exception in thread "main" java.io.IOException: /home/nifi-1.6.0/run directory does not have read/write privilege Thanks @Matt Clarke @Jay Kumar SenSharma

I have installed Nifi-1.6.0 and when I fire the command `./nifi.sh start` in terminal, it is showing `Exception in thread "main" java.io.IOException: /home/nifi-1.6.0/run directory does not have read/write privilege `. Although on browser GUI, Nifi is coming well on `localhost:8080/nifi `.
