java.net.UnknownHostException

Macula: Macula: nodename nor servname provided, or not known

Samebug tips1

When kafka creates new consumers, it simply concatenate the name of your VM to generate the consumer id. So, your VM resolves localhost as the name of your VM, not whatever you had set. To solve, add kafka(or the name of VM) plus address to /etc/hosts
