Kafka console consumer not receiving messages from console producer

[#1]

I recently setup a cloudera quickstartVM using docker image and setup Kafka parcel in it. After successful installation, i see that all the services are running in green status (including Kafka and zookeeper). However, when I follow the below commands of kafka CLI i don't see consumer getting messages.

Any help is greatly appreciated CDHv 5.13 CDK 4.0 (kafka 2.1)- through parcel.

kafka-topics --create quickstart.cloudera:9092 --replication-factor 1 --partitions 1 --topic test3 --zookeeper quickstart.cloudera:2181

topic created successfully on console.

Console Consumer (CLI terminal 1):
kafka-console-consumer --bootstrap-server quickstart.cloudera:9092 --topic test3

consumer started on console in Terminal 1

Console Producer:
kafka-console-producer --broker-list  quickstart.cloudera:9092 --topic test3

Producer created in Terminal 2. Now, when i type anything in console of Terminal 2 (producer), the consumer terminal doesn't show anything.

Please suggest what is missing here. I need help to debug this situation.

kafka-topics --zookeeper quickstart.cloudera:2181 --describe --topic test4

I removed CDK 4.0 and instead added CDK 3.1 (it gets kafka 1.0.1). Now, the consumer is getting the messages on console. There seems to be some issue with CDK 4.0 integration.
