Minor Description
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:
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$)
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.
