> kafka-topics.sh --describe with --zookeeper throws error when there is no
> topic
> -------------------------------------------------------------------------------
>
> Key: KAFKA-8679
> URL: https://issues.apache.org/jira/browse/KAFKA-8679
> Project: Kafka
> Issue Type: Bug
> Reporter: Weichu Liu
> Priority: Minor
>
> h3. Step to Reproduce:
> First, start a Kafka server (2.2.0+), with no topic on it.
> Then run `kafka-topics.sh --describe --zookeeper ...:2181` to get topic
> details
> h3. Expected Behavior
> Expected Behavior should be the command prints nothing and return 0.
> h3. Actual Behavior
> The command throws an exception and exit with 1.
> {code}
> $ kafka_2.12-2.2.1/bin/kafka-topics.sh --describe --zookeeper localhost:2181
> Error while executing topic command : Topics in [] does not exist
> [2019-07-18 06:29:21,336] ERROR java.lang.IllegalArgumentException: Topics in
> [] does not exist
> at
> kafka.admin.TopicCommand$.kafka$admin$TopicCommand$$ensureTopicExists(TopicCommand.scala:416)
> at
> kafka.admin.TopicCommand$ZookeeperTopicService.describeTopic(TopicCommand.scala:332)
> at kafka.admin.TopicCommand$.main(TopicCommand.scala:66)
> at kafka.admin.TopicCommand.main(TopicCommand.scala)
> (kafka.admin.TopicCommand$)
> {code}
> h3. Others
> IIRC, the version before 2.2.0 did not throw exceptions.
> Also, {{--describing}} with {{--bootstrap-server}} will exit 0 and print
> nothing.
> Also {{--list}} with either {{--bootstrap-server}} and {{--zookeeper}} will
> also exit 0 and prints nothing.
> I did some quick search and seems this issue is introduced by
> https://issues.apache.org/jira/browse/KAFKA-7054. I didn't check which exact
> line caused the exception. Hope that will help.
