Kafka throws java.nio.channels.ClosedChannelException

When I try to use messages from the kafka server hosted in ec2 using the kafka console tool (V 0.9.0.1, I think it uses the old consumer APIs) I get the following exception. How can I overcome this?

#. / kafka-console-consumer.sh --zookeeper zookeeper1.xx.com:2181 --topic MY_TOPIC - from the start

The reason for the exclusion of the original private channel is the presence of a DNS problem that I decided by editing the local hosts file

This is actually a WARNING - it doesn't matter. Maybe your topic is spoiled? Try to recreate the theme.
