------------------------------

             Summary: NullPointerException in ConsoleConsumer
                 Key: KAFKA-897
                 URL: https://issues.apache.org/jira/browse/KAFKA-897
             Project: Kafka
          Issue Type: Bug
          Components: consumer
    Affects Versions: 0.8
            Reporter: Colin B.
            Assignee: Neha Narkhede
            Priority: Minor


The [protocol document|https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol#AGuideToTheKafkaProtocol-Messagesets] mentions that keys and values in message sets can be null. However the ConsoleConsumer throws a NPE when a null is passed for the value.
