> If a producer publishes data to topic "foo/foo", the Kafka server ends up creating an invalid directory structure on the server. This corrupts the zookeeper data structure for the topic - /brokers/topics/foo/foo. This leads to rebalancing failures on the consumer as well as errors on the zookeeper based producer. 
> We need to harden the invalid topic handling on the Kafka server side to avoid this.
