You need to start the zookeeper server first  So first go to kafka bin windows and run  zookeeper-server-start bat       config zookeeper properties   then in the same folder with a new cmd windows start the kafka servers by running  kafka-server-start bat       config server properties      Note  if you starting it for the first time then there are certain   changes to be made in these files   then inside kafka bin windows run  kafka-topics bat --zookeeper localhost 2181 --list   to list down all the topics existing

You have a stale version of the package with commands that no longer accept zookeeper but rather bootstrap-server as the connection  Confluent will then connect with Zookeeper internally    https   www confluent io download   5 3 or greater

Kafka uses ZooKeeper so you need to first start a ZooKeeper server if you don t already have one    If you do not want to install and have a separate zookeeper server  you can use the convenience script packaged with kafka to get a quick-and-dirty single-node ZooKeeper instance    Starting the single-node Zookeeper instance    bin zookeeper-server-start sh config zookeeper properties   Starting the Kafka Server   bin kafka-server-start sh config server properties   Listing the Topics available in Kafka    bin kafka-topics sh --list --zookeeper localhost 2181

Kafka 2 2 and up  Newer versions of Kafka no longer requires ZooKeeper connection string to list topics  but can directly go via the Kafka brokers  kafka-topics sh is provided in the bin  folder when downloading Kafka  To list topics  do the following   bin kafka-topics sh --list --bootstrap-server  lt BROKER-LIST gt

The Kafka clients no longer require zookeeper but the Kafka servers do need it to operate   You can get a list of topics with the new AdminClient API but the shell command that ship with Kafka have not yet been rewritten to use this new API   The other way to use Kafka without Zookeeper is to use a SaaS Kafka-as-a-Service provider such as Confluent Cloud so you don   t see or operate the Kafka brokers  and the required backend Zookeeper ensemble     For example on Confluent Cloud you would just use the following zookeeper free CLI command   ccloud topic list

Kafka requires zookeeper and indeed the list of topics is stored there  hence the kafka-topics tool needs to connect to zookeeper too  kafka-clients apis in the newer versions no longer talk to zookeeper directly  perhaps that s why you re under the impression a setup without zookeeper is possible  It is not  as kafka relies on it internally  For reference see  http   kafka apache org documentation html quickstart Step 2      Kafka uses ZooKeeper so you need to first start a ZooKeeper server if you don t already have one
