hi all

we run the following command on kafka machine in order to view/print the topics names

we can see that its fails on

Caused by: java.net.BindException: Address already in use 

but without to print also the port number

./kafka-topics.sh --zookeeper zookeeper1:2181 --list 

To enable GC log rotation, use -Xloggc:<filename> -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=<num_of_files>
where num_of_file > 0
GC log rotation is turned off

@Michael Bronson

Zookeeper's usually have the same port so I suggest you have a look at the brokers. Please have a look at my response to a similar problem
