Hi, I recently started to read up in kafka. Now I would like to start working on cloudera but I have some problems with sending messages. I created a a topic with following code: $ kafka-topics --create --zookeeper 127.0.0.1:2181 --replication-factor 1 --partitions 1 --topic test --> it worked then i tried to send some messages with following code: $ kafka-console-producer --broker-list 127.0.0.1:2181 --topic test --> doesnt work but as soon I write a message, i get several Warnings and an Error message: WARN [Producer clientId=console-producer] Bootstrap broker 127.0.0.1:2181 (id: -1 rack: null) disconnected (org.apache.kafka.clients.NetworkClient) ... ERROR Error when sending message to topic test with key: null, value: 9 bytes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback) org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after 60000 ms. Does someone can help me to fix this problem?

What version of Cloudera Kafka/CDH are you testing?
Can you do the following:
kafka-topics --zookeeper <zkhost>:2181 --list
kafka-topics --zookeeper <zkhost>:2181 --describe --topic test
