WARN Error while fetching metadata with correlation id 1 : {MY_TOPIC?=INVALID_TOPIC_EXCEPTION} (org.apache.kafka.clients.NetworkClient)


When I run the following command with kafka 0.9.0.1, I get these warnings[1]. Can you please tell me what is wrong with my topics? (I'm talking to the kafka broker which runs in ec2)

./kafka-console-consumer.sh --new-consumer --bootstrap-server kafka.xx.com:9092 --topic MY_TOPIC?
