Shuai Zhang resolved KAFKA-5596.
--------------------------------
Resolution: Not A Problem
> TopicCommand methods fail to handle topic name with "."
> -------------------------------------------------------
>
> Key: KAFKA-5596
> URL: https://issues.apache.org/jira/browse/KAFKA-5596
> Project: Kafka
> Issue Type: Bug
> Components: admin
> Affects Versions: 0.10.0.0, 0.10.0.1, 0.10.1.1, 0.10.2.1, 0.11.0.0
> Reporter: Shuai Zhang
> Fix For: 0.12.0.0
>
>
> When there is one topic which name includes ".", then we invoke *list*,
> *describe*, *alter*, *delete* functions and set this topic name, those
> functions will not only operate this topic, but also operate all other topics
> that have same name regex pattern.
> For example, there are two topics on Kafka cluster:
> * test.a
> * test_a
> If you run command "--describe --topic test.a", it will return both of
> *test.a* and *test_a*. Other functions have the same effect.
