Grant Henke commented on KAFKA-2337:
------------------------------------
This patch:
- Checks all topic creation including auto-create
- Fails with InvalidTopicException when topics collide (periods and underscores
in the same position)
- Warns when a topic with a period or underscore is created via kafka-topics.sh
> Verify that metric names will not collide when creating new topics
> ------------------------------------------------------------------
