Thanks for your answer, but the zookeeper ensemble is running and ports are ok.

Start the zookeeper ensemble first before starting Kafka cluster. They need
to select a leader and ensure that they all come online OK. Check port
2181, 2888, 3888 using
netstat -plten|egrep '2181|2888|3888'
tcp 0 0 :::2181 :::*
LISTEN 1005 9934134 29170/java
tcp 0 0 ::ffff:50.140.197.217:2888 :::*

tcp 0 0 ::ffff:50.140.197.217:3888 :::*
LISTEN 1005 9935493 29170/java
P.S. I assume you are talking about Apache Kafks here.
