Vahid Hashemian created KAFKA-4483:
--------------------------------------

             Summary: Exception when creating topics
                 Key: KAFKA-4483
                 URL: https://issues.apache.org/jira/browse/KAFKA-4483
             Project: Kafka
          Issue Type: Bug
            Reporter: Vahid Hashemian
            Priority: Blocker


The latest trunk codebase seems to expose a critical bug. Steps to reproduce on a fresh server:

1. {{git clone https://github.com/apache/kafka.git}}
    {{cd kafka}}
    {{gradle}}
    {{./gradlew jar}}

2. {{bin/zookeeper-server-start.sh config/zookeeper.properties}}
3. {{bin/kafka-server-start.sh config/server.properties}}
4. {{bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test}}

Step 4 causes this exception on the server:
{code}

{code}

However, the topic seems to be created successfully.

5. Stop the server.
6. Restart the server. This causes an exception and shuts down the server.
