Can someone tell me why I'm getting this error?

Thank You

HI@akhtar,

You get this error because before stating the kafka server you have to start zookeeper server.

In kafka zookeeper is used to manage the kafka server.

$ ./bin/zkServer.sh start

$ ./bin/zkCli.sh

$ ./bin/kafka-server-start.sh config/server.properties

Hope this will work
