Jakub Scholz created KAFKA-8053: ----------------------------------- Summary: kafka-topics.sh gives confusing error message when the topic doesn't exist Key: KAFKA-8053 URL: https://issues.apache.org/jira/browse/KAFKA-8053 Project: Kafka Issue Type: Bug Reporter: Jakub Scholz
The kafka-topics.sh utility gives a confusing message when the topic it is called with doesn't exist or when no topics exist at all: {code} bin/kafka-topics.sh --zookeeper localhost:2181 --describe --topic xxx Error while executing topic command : Topics in [] does not exist [2019-03-06 13:26:33,982] 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} It tries to list the topics, but because list of topics is always empty, it always prints just `[]`. The error message should be more useful and instead list the topic passed by the user as the parameter or not try to list anything at all. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
