Jiangjie Qin commented on KAFKA-3018:
-------------------------------------
I am not sure if we should let producer to check if a topic name is valid or
not. At the end of the day, it is the server which determines whether a topic
name is valid or not. Would it help if we improve the error message of
InvalidTopicException a little bit to give some possible causes?
> Kafka producer hangs on producer.close() call if the producer topic contains
> single quotes in the topic name

> While creating topics with quotes in the name throws a exception but if you
