Hi Kiran, Can you attach your configuration files not in a .zip?
Most likely your broker isn't using the correct hostname:port to connect to ZooKeeper. Although if you're using ZooKeeper SASL, you may have a SASL misconfiguration. Set the `sun.security.krb5.debug` JVM property to `true` to get SASL debug messages.
